To find the zeros of the quadratic equation y = x^2 - 8x + 15, we set y equal to zero and solve for x:
0 = x^2 - 8x + 15
This equation can be factored as:
0 = (x - 5)(x - 3)
Setting each factor equal to zero, we get:
x - 5 = 0 ---> x = 5
x - 3 = 0 ---> x = 3
Therefore, the zeros of the quadratic equation are x = 5 and x = 3.
0 = x^2 - 8x + 15
This equation can be factored as:
0 = (x - 5)(x - 3)
Setting each factor equal to zero, we get:
x - 5 = 0 ---> x = 5
x - 3 = 0 ---> x = 3
Therefore, the zeros of the quadratic equation are x = 5 and x = 3.
