Solve by completing the square: I think you have a typo here: -6 should be -6x
x%5E2+-6x+-+5+=+0 Add 5 to both sides.
x%5E2+-+6x+=+5 Add the square of half the x-coefficient, that's %28%281%2F2%29%28-6%29%29%5E2+=+9 to both sides.
x%5E2+-+6x+%2B+9+=+14 Factor the left side of the equation.
%28x+-+3%29%5E2+=+14 Take the square root of both sides then add 3 to both sides.
x+=+3+%2B-+sqrt%2814%29
The roots are:
x+=+3+%2B+sqrt%2814%29
x+=+3+-+sqrt%2814%29
