Question 675595
use the quadratic formula to find any x-intercepts on the graph of the equation:
{{{y=x^2-8x-6 }}}
quadratic formula:
{{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}}
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
