Question

Choose the correct simplification of
9x^2(4x + 2x^2 – 1) PLEASE EXPLAIN !!!!!!

Answer 1

multiply each term in the second parentheses by \(9x^2\)

Answer 2

\[9x^2\times 4x+9x^2\times 2x^2-9x^2\] is a start

Answer 3

thats all ?

Answer 4

no, now you have to compute what you get

Answer 5

for example \(9\times 4=36\) and \(x\times x^2=x^3\) so teh first term is
\[36x^3\]

Answer 6

hmm...wouldn't simplifying be factoring?

Answer 7

okay and then you put all the terms in one equation right

Answer 8

@satellite73 36x4 + 18x3 − 9x2 answer??
