Example Question #41 : Quadratic Equations And Inequalities
Expand out the following expression.
This problem uses the distributive property. When using the distributive property on two sums, we apply the FOIL method. FOIL is an acronym that means, First, Outer, Inner, Last. This means we multiply the first term by the first term, the outer term by the outer term, the inner term by the inner term, and the last term by the last term. Take all of these products and add them together. To put this in a more general equation:
Applying this formula to our problem we have,
And thus, our answer is
Example Question #41 : Quadratic Equations And Inequalities
Use FOIL to multiply:
Recall that FOIL means multiplying the first terms, then outside terms, next inside terms, and finally, the last terms:
Then, combine like terms to get your answer of
Example Question #43 : Quadratic Equations And Inequalities
Expand:
Use the FOIL method to expand the binomials.
Simplify the terms on the right side of the equal sign.
Combine like-terms.
The answer is:
Example Question #42 : Quadratic Equations And Inequalities
Multiply:
Use FOIL to multiply these binomials.
First multiply the first terms
then the outside terms
next the inside terms
and finally, the last terms
That gives you
Combine like terms to get your final answer of
Example Question #43 : Quadratic Equations And Inequalities
Multiply:
Remember to use FOIL when multiplying.
Multiply the first terms
then the outside terms
next the inside terms
and finally, the last terms
Put those all together to get your answer:
Example Question #46 : Quadratic Equations And Inequalities
Use the FOIL method to simplify:
Distribute the first term of the binomial with both terms of the second binomial.
Distribute the second term of the binomial with both terms of the second binomial.
Add the terms together.
The answer is:
Example Question #1342 : Algebra Ii
To multiply these two binomials, use FOIL.
Multiply the first terms
then the outside terms
next the inside terms
and finally the last terms
Put those all together to get:
Combine like terms to get your final answer of
Example Question #1342 : Algebra Ii
Expand:
Expand by using the FOIL method.
Simplify each term.
Combine like terms.
The answer is:
Example Question #24 : Foil
Compute:
Expand the expression by using the FOIL method.
Simplify all the terms.
Combine like-terms.
The answer is:
Example Question #44 : Quadratic Equations And Inequalities
Use the FOIL method to expand:
Multiply the first term of the first binomial with the quantity of the second binomial.
Multiply the second term of the first binomial with the quantity of the second binomial. Include the negative sign.
Add and combine like-terms.
The answer is:
