X + 2 whole cube is equals to x cube minus 4 it is a quadratic equation or not​

Answer»

Answer:

yes.

Step-by-step EXPLANATION:

(X + 2)³ = x³ - 4

x³ + 2³ + 3(x)(2)[x + 2] = x³ - 4

8 + 6x[x + 2] = -4

6x² + 12x = -12

6x² + 12x - 12 = 0

6(x² + 2x - 2) = 0

x² + 2x - 2 = 0

Clearly, the above eqn is in the form ax² + bx + C = 0, therefore, it is quadratic equation.

Hope this helps you!!!
