Answer 2

The formula for area of a rectangle is

A = lw

Right?

Answer 3

YES

Answer 4

And in this case l = (3x^2 + x - 3) and w = (2x^3 - 4x + 3) , right?

Answer 5

yes

Answer 6

So this must mean that

A = (3x^2 + x - 3)(2x^3 - 4x + 3) correct?

Answer 7

yes

Answer 8

NEVERMIND I GOT IT

Answer 9

You do? What did you get?

Answer 10

6x^5+2x^4−18x^3+5x^2+15x−9

Answer 11

How did you get that? Can you show the work you did to get that?
