Question

What’s the x-intercept of y=x2-4x-12

Answer 1

Answer: (6, 0) and (-2 0)

Step-by-step explanation:x intercept is calculated by plugging in 0 to y:

0 = x2 - 4x - 12

we factor out above equation:

(x - 6) (x + 2) = 0

so, x = 6 or x = -2

so we have two x intercepts:

(6, 0) and (-2, 0)
