Hi,         
x-intercepts are dtyermined when y = 0
 x^2 - 3x + 2 = 0
factoring
(x-2)(x-1) = 0 Note:SUM of the inner product(-2x) and the outer product(-x) = -3x
(x-2)= 0    x = 2  x -Intercept Pt(2,0)
(x-1) = 0   x = 1  x -Intercept Pt(1,0)


 x^2-1 = 0
    x^2 = 1
    x = ± 1        x -Intercepts: Pt(1,0)and Pt(-1,1)
