Which expression is equivalent to (9x2 + 2x – 7)(x – 4)? A. x(9x2 + 2x – 7) + 4(9x2 + 2x – 7) B. (9x2 + 2x – 7)(x) + (9x2 + 2x – 7)(–4) C. x(9x2 + 2x – 7) – 4 D. –4x(9x2 + 2x – 7)

I'm pretty sure its B. (9x2+2x-7)(x)+(9x2+2x-7)(-4)
Because its just splitting up the (x-4) and if you add the answers together then you get the same answer as the original
