Answer #1

6x^2 - 2x^4 + 4 + 3x

ok come on, this isnt hard… which one has the most xs and which one has the least?

-2x4 + 6x2 + 3x + 4

(2x + 3)(3x + 4) = 6x2 + 8x +9x + 12 = 6x2 + 17x + 12

A.2x(3x + 4) + 3(3x + 4) = 6x2 + 8x + 9x + 12 = 6x2 + 17x + 12

B.2x(2x + 3) + 3(3x + 4)

C.2x(3x + 4)

D.2x(3x + 4) + (3x + 4)

(x + 4) (x +4) = x2 + 4x + 4x + 16 = x2+8x +16
