x%5E2-7x=5
First make one side of the equation zero. Subtracting 5 from each side:
x%5E2-7x-5=0

Now use the Quadratic Formula:
x+=+%28-%28-7%29%2B-sqrt%28%28-7%29%5E2-4%281%29%28-5%29%29%29%2F2%281%29
Simplifying...
x+=+%28-%28-7%29%2B-sqrt%2849-4%281%29%28-5%29%29%29%2F2%281%29
x+=+%28-%28-7%29%2B-sqrt%2849%2B20%29%29%2F2%281%29
x+=+%28-%28-7%29%2B-sqrt%2869%29%29%2F2%281%29
x+=+%287%2B-sqrt%2869%29%29%2F2
which is short for:
x+=+%287%2Bsqrt%2869%29%29%2F2 or x+=+%287-sqrt%2869%29%29%2F2
