To find the x-intercepts of the quadratic function y = 2x² + 4x - 16, we set y to 0 and solve for x.

2x² + 4x - 16 = 0

To solve this quadratic equation, we can use factoring, completing the square, or the quadratic formula. In this case, factoring is convenient.

The factored form of the quadratic equation is:

2(x - 2)(x...
