Which of the following expressions is equivalent to: 6x (m2 +yx2 _–_3)?

6xm2 + 6yx2 -18x

6xm2 + 6yx3 -18

6xm2 + 6yx3 -18x

6xm2 + 7x3 -18

xm2 + 7x3 -18

Explanation

6x (m2 +yx2 _–_3)= 6x∙m2 + 6xyx2 – 6x∙3= 6xm2 + 6yx3 -18x (Use Distributive Property)

Which expression is equal to ?

Explanation

In this problem, we are to multiply the two binomials using the FOIL method. This method stands for the order in which you multiply the variables. F stands for the first term of each binomial. O stands for the outside terms, meaning the first term of the first binomial and the last term of the second. I stands for the inside terms, meaning the second term of the first binomial and the first term of the second. L stands for the last term of each binomial. Once you do this, you simply add each part together to recieve your polynomial answer. Here is how our problem is solved:
