Question 766424: Can someone please help me solve this? Thank You!!
Use the quadratic formula to find any x-intercepts on the graph of the equation.
y=x^2-6x-2
Type all x-intercepts below. Select the correct choice below to fill in any answer boxes within your choice.
A. x=_____ ( simplify your answer. Type an exact answer, using radicals as needed. Use a comma to separate answers as needed )
B. There is no x-intercept.

You can put this solution on YOUR website!
y=x^2-6x-2,
solve using the quadratic equation
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
============================================================
where b = -6, a=1, c=-2
x+=+%286+%2B-+sqrt%28+-6%5E2-4%2A1%2A-2+%29%29%2F%282%2A1%29+
===========================================================
x=6.32, x=-.32
===========================================================
now look at the graph of y=x^2-6x-2
graph%28+600%2C+400%2C+-10%2C+10%2C+-15%2C+15%2C+x%5E2+-6x+-2%29
=========================================================
we can see from the graph that the solutions to the quadratic equation
give us the two x intercepts 6.32 and -.32
cheers!
