x%5E2-3x=7x-2
First get the equation into the proper form
ax%5E2%2Bbx%2Bc=0
x%5E2-3x=7x-2
x%5E2-3x-7x%2B2=7x-2-7x%2B2 Add (-7x+2) to both sides.
x%5E2-10x%2B2=0
Now you're ready for the quadratic formula.
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%28-%28-10%29+%2B-+sqrt%28+%28-10%29%5E2-4%2A1%2A%282%29+%29%29%2F%282%2A1%29+
x+=+%28%2810%29+%2B-+sqrt%28+%28100-8+%29%29%29%2F%282%29+
x+=+%28%2810%29+%2B-+sqrt%28+%28100-8+%29%29%29%2F%282%29+
x+=+%28%2810%29+%2B-+sqrt%2892%29%29%2F%282%29+
