No,it is not a quadratic equation.

(B) Given equation: $x(x+1)+8=(x+2)(x-2)$Expanding both sides:$x^2 + x + 8 = x^2 - 4$Subtracting $x^2$ from both sides:$x + 8 = -4$$x + 12 = 0$Since the highest power of the variable $x$ is $1$,this is a linear equation,not a quadratic equation. $A$ quadratic equation must have the form $ax^2 + bx + c = 0$ where $a \neq 0$.
