Divide the expression.

1. (7x^3+52x^2-95x+31) ÷ (7x-4)

Answer 1

The first step is to write out the problem in polynomial long division form. See attached

Answer 2

have you done that so far?

Answer 3

Yes

Answer 4

Focus on the terms I've circled in red (see attached).

Fill in the blank

Answer 9

yes

Answer 10

So we write 7x^2 over the x^2 term like this

Answer 11

then we multiply 7x^2 by the (7x-4) term

Answer 18

yeah
