Answer 1

what is the question plz write in order

Answer 2

Step-by-step explanation:

x + 2)3 = 2x(x2 – 1)

                  We have:

                  (x + 2)3 = 2x(x2 – 1)

                  x3 + 3x2(2) + 3x(2)2 + (2)3 = 2x3 – 2x

                  ⇒ x3 + 6x2 + 12x + 8 = 2x3 – 2x

                  ⇒ x3 + 6x2 + 12x + 8 – 2x3 + 2x = 0

                  ⇒ –x3 + 6x2 + 14x + 8 = 0

                  Since –x3 + 6x2 + 14x + 8 is a polynomial of degree 3

                  ∴ (x + 2)3 = 2x(x2 – 1) is not a quadratic equation.
