What is the solution to 2x2+8x=x2-16 ? x=4 x=-2 x=2 x=4

The solution of the quadratic equation 2x² + 8x = x² - 16 is given as a negative of 4.What is a factorization?It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.The equation is given below.2x² + 8x = x² - 16 Then on simplifying, we have        x² + 8x + 16 = 0x² + 4x + 4x + 16 = 0       (x + 4)(x + 4) = 0               (x + 4)² = 0                         x = -4More about the factorization link is given below.
