use the quadratic formula to find any x-intercepts on the graph of the equation:
y=x%5E2-8x-6+
quadratic formula:
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
a=1, b=-8, c=-6
x=[-(-8)±√((-8)^2-4*1*(-6))]/2(1)
x=[8±√(64+24)]/2
x=[8±√(88)]/2
x=[8±9.38]/2
x=17.38/2≈8.69
or
x=-1.38/2≈-0.69
x-intercepts: 8.69 and -0.69
