Question

Find the x intercepts for the parabola defined by the equation below. y=x^2-9x+18​

Answer 1

x intercepts are where the y value is 0. So, set y=0 and solve
0=x^2-9x+18
0=(x-6)(x-3)
x=6,3
The x intercepts are (6,0) and (3,0)
if you want to check, try these (x, y) pairs in the original equation.
