x%5E2%2B13=4x
x%5E2-4x%2B13=0...use quadratic formula

x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+

x+=+%28-%28-4%29+%2B-+sqrt%28+%28-4%29%5E2-4%2A1%2A13+%29%29%2F%282%2A1%29+

x+=+%284+%2B-+sqrt%28+16-52+%29%29%2F2+

x+=+%284+%2B-+sqrt%28+-36+%29%29%2F2+

x+=+%284+%2B-+sqrt%28+-1%2A36+%29%29%2F2+

x+=+%284+%2B-+6i%29%2F2+
solutions:

x+=+%284+%2B+6i%29%2F2+
x+=+4%2F2+%2B+6i%2F2+
highlight%28x+=+2+%2B+3i%29+

and

x+=+%284+-6i%29%2F2+
x+=+4%2F2+-+6i%2F2+
highlight%28x+=+2+-3i%29+
