(x + 7)(x - 3) **Weegy:** 1/x+8=x-3/12
Multiply both sides by (x+8) gives 1 = (x+8)(x-3)/12
(x+8)(x-3) = 12
x^2 + 5x -36 = 0
Factorising gives
(x+9)(x-4)=0
x = -9 or 4 **User:** (x+1)(x^2+5x-2) **Weegy:** x^(3)+6x^(2)+3x-2 is the answer. (More)

(x + 7)(x - 3)

= x^2 - 3x + 7x - 21

= x^2 + 4x - 21

= x^2 - 3x + 7x - 21

= x^2 + 4x - 21

(x+1)(x^2+5x-2)

= x^3 + 5x^2 + x^2 - 2x + 5x - 2

= x^3 + 6x^2 + 3x - 2

= x^3 + 5x^2 + x^2 - 2x + 5x - 2

= x^3 + 6x^2 + 3x - 2
