User: Find the product. (9x^3 + 2)(x^2 - 7)

Weegy: (x - 2)(x + 7) = x^2 + 5x -14
vchutkan|Points 5755|

User: Factor by grouping. Assume any variable exponents represent whole numbers. x^3 - 4x^2 + 5x - 20

Weegy: The answer is (x? - 5)(x + 4).

(4x^7 + 8x^6 + 12) - (7x^7 - 17x^6 - 11)
= 4x^7 + 8x^6 + 12 - 7x^7 + 17x^6 + 11
= -3x^7 + 25x^6 + 23

x^3 - 4x^2 + 5x - 20
= x^2(x - 4) + 5(x - 4)
= (x - 4)(x^2 + 5)
