Question

(x+2)³=2x(x²-1) is this a qudratic equation?

ANSWER FAST!!!!​

Answer 1

Answer: NO

Step-by-step explanation:

Because after expanding

LHS = x^3+8 +6x^2 + 12x

RHS = 2x^3 - 2x

Bringing all on one side

x^3 + 8 + 6x^2 + 12x - 2x^3 + 2x = 0

The x^3 term still remains

Therefore it is a cubic equation not a quadratic
