Answer» Explanation: x −3x+2)(x+2)=x(x 2 −3x+2)+2(x 2 −3x+2) \PINK{x^3-3x^2+2x^2-6x+4}x 3 −3x 2 +2x 2 −6x+4 \pink{x^3-x^2-4x+4}x 3 −x 2 −4x+4 Lets DIFFERENTIATING x Therefore d/dx{(x^3-x^2-4x+4)}(x 3 −x 2 −4x+4) Lets SUBSTITUTE it {3×x^3-1 \ - 2×x^2-1 \ - 1×4×x^1-1}3×x 3 −1 −2×x 2 −1 −1×4×x 1 −1 Therefore \pink{3x^2-2x-4}3x 2 −2x−4 |
