A2. Which statement is incorrect?

(A) $2 x^{2}-32=2(x-4)(x+4)$

(B) The line $y=x+1$ intersects the x-axis at point $A(-1,0)$.

(C) The lines with equations $y=2 x+2$ and $2 x-y+4=0$ are parallel.

(D) $\sqrt{17^{2}-15^{2}}=2^{3}$

(E) $2^{0}+(-1)^{0}=0$
A2. The statement $2^{0}+(-1)^{0}=0$ is incorrect, as $2^{0}+(-1)^{0}=1+1=2$.
