Example Question #113 : How To Use Foil In The Distributive Property
Multiply. Select the answer that is equivalent to this expression.
Remember, FOIL which stands for the multiplication of the first terms, outer terms, inner terms, and last terms.
First items: x and x
Outside items: x and 5
Inside items: -3 and x
Last items: -3 and 5
Example Question #114 : How To Use Foil In The Distributive Property
Multiply. Select the answer that is equivalent to this expression.
Remember, FOIL which stands for the multiplication of the first terms, outer terms, inner terms, and last terms.
First items: x and x
Outside items: x and -4
Inside items: 4 and x
Last items: 4 and -4
Example Question #115 : How To Use Foil In The Distributive Property
Multiply. Select the answer that is equivalent to this expression.
Remember, FOIL which stands for the multiplication of the first terms, outer terms, inner terms, and last terms.
First items: 2x and 3x
Outside items: 2x and -2
Inside items: 1 and 3x
Last items: 1 and -2
Example Question #116 : How To Use Foil In The Distributive Property
Multiply. Select the answer that is equivalent to this expression.
Recall FOIL, which stands for the multiplication of the first terms, outer terms, inner terms, and last terms.
Firsts: 4x * 4x
Outer: 4x*-5
Inner: 5*4x
Lasts:5*-5
=
=
When the binomials are conjugate pairs (in the form (a + b)(a - b)), the middle term will always drop out since the inside and outside products will sum to zero.
Example Question #121 : How To Use Foil In The Distributive Property
Multiply. Select the answer that is equivalent to this expression.
Simply write it as a pair and FOIL which stands for the multiplication of the first terms, outer terms, inner terms, and last terms.
Example Question #121 : Distributive Property
Multiply. Select the answer that is equivalent to this expression.
Simply write it as a pair and FOIL which stands for the multiplication of the first terms, outer terms, inner terms, and last terms.
Example Question #123 : Distributive Property
Multiply. Select the answer that is equivalent to this expression.
For this question use FOIL which stands for the multiplication of the first terms, outer terms, inner terms, and last terms.
Example Question #122 : How To Use Foil In The Distributive Property
Multiply. Select the answer that is equivalent to this expression.
Don't be intimidated, just FOIL which stands for the multiplication of the first terms, outer terms, inner terms, and last terms. The answer is rearranged in the order of the powers of x.
Example Question #121 : Distributive Property
Expand the following expression:
Expand the following expression:
To begin, we need to realize that we cannot simply square both inside terms and call it a day. First, let's rewrite what we are given
Next, we can use FOIL, which stands for
First
Outer
Inner
Last
I've color coded each set, now we just need to simplify and combine like terms to get:
Example Question #41 : Quadratic Equations
Use the distributive property (use FOIL method) to solve the following
Remember that FOIL stands for First, Outer, Inner, Last. We will add up the different parts. If we had an expression
than we would have
First:
Outer:
Inner:
Last:
For this problem we have
First:
Outer:
Inner:
Last:
Adding these together gives
check: let's add the first two numbers and multiply that by the sum of the last two,
