Hi
using the quadratic formula to solve
x^2/4-x/2=1
x^2 - 2x = 4
x^2 - 2x - 4 = 0
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%282+%2B-+sqrt%28+20+%29%29%2F%282%29+
x+=+%282+%2B-+sqrt%28+4%2A5+%29%29%2F%282%29+
x+=+%282+%2B-+2%2Asqrt%28+5+%29%29%2F%282%29+
x+=+highlight%281+%2B-+sqrt%28+5+%29%29
