Example Question #11 : Algebraic Fractions
Simplify:
(2x + 4)/(x + 2)
2x + 2
2
x + 1
x + 4
x + 2
2
(2x + 4)/(x + 2)
To simplify you must first factor the top polynomial to 2(x + 2). You may then eliminate the identical (x + 2) from the top and bottom leaving 2.
Example Question #1021 : Algebra
Simplify the following expression:
Factor both the numerator and the denominator:
After reducing the fraction, all that remains is:
Example Question #5 : How To Simplify A Fraction
Simplify:
None of the other answers
With this problem the first thing to do is cancel out variables. The x2 can all be divided by each other because they are present in each system. The equation will now look like this:
Now we can see that the equation can all be divided by y, leaving the answer to be:
Example Question #6 : How To Simplify A Fraction
Simplify the given fraction:
120 goes into 6000 evenly 50 times, so we get 1/50 as our simplified fraction.
Example Question #13 : Algebraic Fractions
Simplify the given fraction:
125 goes into 2000 evenly 16 times. 1/16 is the fraction in its simplest form.
Example Question #14 : Algebraic Fractions
Simplify the following expression:
Following this equation, you divide 4 by 8 to get 1/2. When a variable is raised to an exponent, and you are dividing, you subtract the exponents, so 6 – 3 = 3.
Example Question #12 : How To Simplify A Fraction
Reduce the fraction:
The numerator and denominator are both divisible by 12. Thus, we divide both by 12 to get our final answer.
If we instead divide by another common factor, we may need to complete the process again to make sure that we have completely reduced the fraction.
In mathematical words we get the following:
