what are the zeros of y=x^2-2x-15

Answer 1

To find the zeros of the quadratic equation y = x^2 - 2x - 15, we set y equal to zero and solve for x:

0 = x^2 - 2x - 15

This equation can be factored as:

0 = (x - 5)(x + 3)

Setting each factor equal to zero:

x - 5 = 0 or x + 3 = 0

Solving for x:

x = 5 or x = -3

Therefore, the zeros of the equation are x = 5 and x = -3.
