Simplify or expand each expression and then classify it by its degree and number of terms.

answer: what are the following choices

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

x (x+6)^2

which is choice b

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
