Example Question #13 : Simplifying Polynomials

Simplify

$\frac{2x^2-4x-30}{5-x}$

Possible Answers:

x+5

x+3

2x+6

-2x-6

2x+10

Correct answer:

-2x-6

Explanation:

The polynominal breaks down to 2(x-5)(x+3) , and once you factor out a from the denomintator and cancel, you are left with -2(x+3) .

Example Question #14 : Simplifying Polynomials

Simplify

$\frac{x^3+(x+2)^2+2x^2-x-3}{(x+1)^2}$

Possible Answers:

x^3+2x^2+x+2

$\frac{x^2+3x+3}{x-1}$

$\frac{x^3+3x^2+3x+1}{(x+1)^2}$

x+1

Correct answer:

x+1

Explanation:

First, you FOIL the binomial in the numerator. Then combine like terms, which simplifies the numerator to x^3+3x^2+3x+1 , which can be further simplified to (x+1)^3 . The coefficients for this can be found in Pascal's Triangle, so they do not have to be memorized. Once the numerator and denominator are in the same base, the exponents cancel out, leaving you with the correct answer.

Example Question #14 : Simplifying Polynomials

Simplify the following expression

$8y + 4x^{2} -3y^{2} + y +3x^{2} -x$

Possible Answers:

$9y + 7x^{2} + 3xy^{2}$

$7x^{2}-x+9y-3y^{2}$

$3y^{2}+x+9y+7x^{2}$

Expresion cannot be simplified any further

$6y^{2}+6x^{2}$

Correct answer:

$7x^{2}-x+9y-3y^{2}$

Explanation:

Simplify a polynomial expression by combining like terms. Like terms are those that have exactly the same variable and degree (exponent). This one is reasonably simple with only addition and subtraction of polynomials involved. The like terms are...

8y + y = 9y

$4x^{2}+3x^{2}=7x^{2}$

The remaining terms are $-3y^{2}$ and

Combine everything together as done below. As long as the signs are right, order of operations lets you arrange the final answer various ways, but you should know this be able to identify the correct answer even if yours was arranged differently.

$9y+7x^{2}-3y^{2}-x$

Example Question #4 : How To Add Polynomials

Simplify

$(2x^{2}-5) + (4x^{3}-3x^{2}+2x-1)$

Possible Answers:

$4x^{3}-x^{2}+2x-6$

$5x^{2}+2x-6$

$5x^{2}-6$

$4x^{3}-6x^{2}+1x-6$

Correct answer:

$4x^{3}-x^{2}+2x-6$

Explanation:

$(2x^{2}-5) + (4x^{3}-3x^{2}+2x-1)$

To simplify you combind like terms:

$(4x^{3}\boldsymbol{-3x^{2}+2x^{2}} +2x\boldsymbol{-1-5)}$

Answer:

$4x^{3}-x^{2}+2x-6$

Example Question #11 : Intermediate Single Variable Algebra

Simplify.

$(4a^{2}b+2ab) - (3a^{2}b+4ab+2)$

Possible Answers:

$a^{2}b+6ab+2$

$a^{2}b-2ab-2$

$a^{2}b+2ab-2$

$a^{2}b-6ab-2$

Correct answer:

$a^{2}b-2ab-2$

Explanation:

Simplify

$(4a^{2}b+2ab) - (3a^{2}b+4ab+2)$

Distribute the negative: $\boldsymbol{-}3a^{2}b\boldsymbol{-}4ab\boldsymbol{-}2$

Then combinde like terms

$\mathbf{\boldsymbol{-}3a^{2}b+4a^{2}b}(\mathbf{\boldsymbol{-}4ab+2ab})\boldsymbol{-}2$

Answer:

$a^{2}b-2ab-2$

Example Question #4 : How To Subtract Polynomials

Subtract:

$(7.5x^{2} + 1.4x - 4.6) - (x^{2} + 6.2x - 3.5)$

Possible Answers:

$6.5x^{2} - 4.8x - 1.1$

$7.5x^{2} - 4.8x - 1.1$

$7.5x^{2} +7.2x - 1.1$

$6.5x^{2} +7.2x - 1.1$

$6.5x^{2} - 4.8x - 8.1$

Correct answer:

$6.5x^{2} - 4.8x - 1.1$

Explanation:

$(7.5x^{2} + 1.4x - 4.6) - (x^{2} + 6.2x - 3.5)$

$= 7.5x^{2} + 1.4x - 4.6 - x^{2} - 6.2x + 3.5$

$= 7.5x^{2} - 1x^{2} + 1.4x- 6.2x - 4.6 + 3.5$

$= 6.5x^{2} - 4.8x - 1.1$

Example Question #21 : Simplifying Polynomials

Simplify the following expressions by combining like terms:

$-\left ( -3x^{3} +2x^{2} -xy -5x-13\right ) + x^{5} -4x^{4} -2x^{3} -9xy$

Possible Answers:

$x^{5}-4x^{4}-5x^{3}-2x^{2}-10xy+13$

$x^{5}-4x^{4} +x^{3}-2x^{2} -13$

$x^{5}-4x^{4}-5x^{3}-2x^{2} +13$

$x^{5}-4x^{4}+x^{3}-2x^{2}-8xy+5x+13$

$x^{5}-4x^{4} +x^{3} +2x^{2}-8xy -13$

Correct answer:

$x^{5}-4x^{4}+x^{3}-2x^{2}-8xy+5x+13$

Explanation:

Distribute the negative sign through all terms in the parentheses:

$3x^{3} - 2x^{2}+xy +5x +13$

Add the second half of the expression, $x^{5}-4x^{4}-2x^{3}-9xy$ to get:

$x^{5}-4x^{4}+x^{3}-2x^{2}-8xy+5x+13$

Example Question #22 : Intermediate Single Variable Algebra

Write as a polynomial in standard form: $(3x - 2y)^{3}$

Possible Answers:

$27x^{3} - 18 x^{2} y + 12 xy^{2} - 8y^{3}$

$27x^{3} - 54 x^{2} y + 36 xy^{2} - 8y^{3}$

$27x^{3} - 8y^{3}$

$27x^{3} + 18 x^{2} y - 12 xy^{2} - 8y^{3}$

$27x^{3} + 54 x^{2} y - 36 xy^{2} - 8y^{3}$

Correct answer:

$27x^{3} - 54 x^{2} y + 36 xy^{2} - 8y^{3}$

Explanation:

$(A -B)^{3} = A^{3} - 3A^{2} B + 3AB^{2} - B^{3}$

Replace: A = 3x, B = 2y :

$(3x -2y)^{3}$

$= (3x)^{3} - 3 (3x) ^{2} (2y) + 3 (3x) (2y)^{2} - (2y)^{3}$

$= 3^{3}x^{3} - 3 \cdot 3^{2} \cdot 2 \cdot x^{2} y + 3 \cdot 3 \cdot 2^{2} \cdot xy^{2} - 2^{3}y^{3}$

$= 27x^{3} - 54 x^{2} y + 36 xy^{2} - 8y^{3}$
