Question

6x(x − 4) − 16x2 − (9x − 1)?

Answer 1

Distribute and collect like terms

Answer 2

Multiply each term by the one in the parenthesis, taking great care of signs.

I'll start you off
\[\rightarrow 6x(x) - (6x)(4) - 16x ^{2} -9x +1\]
\[\rightarrow 6x ^{2} - 24x -16x ^{2}-9x +1\]

Simplify, what do you get?

Answer 3

10x2 − 33x + 1

Answer 4

-10x^2 - 33x +1

Remember @abileneeagle that 6-16=-10
