Question

Is x²-2= (x+2)² is quadric equation or not .give reasons​

Answer 1

Answer:

No it is not a quadratic equations

Step-by-step explanation:

$x ^{2} - 2 = (x + 2)^{2} \\ x^{2} - 2 = {x}^{2} + 4x + 4 \\ {x}^{2} - {x}^{2} - 4x - 4 - 2 = 0 \\ - 4x - 6 = 0 \\ - 2(2x + 3) = 0$

Because the x^2 turm is cancelled from each other. So, this equation not a quadratic equation.
