Answer 1

Answer:

Not quadratic.

Step-by-step explanation:

$x(x + 1) + 8 = (x + 2)(x - 2)$

$x^2 + x + 8 = x^2 - 4$

$x = -12$

Since the 2nd power of an unknown x is not involved, the given equation isn't quadratic.

Answer 2

Answer:

no...it's nt a quadratic eq'n

Step-by-step explanation:

x^2+x+8=x^2-4

x+12=0 is ans....so,nt a quadratic.
