4x^2-x-5=0
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+ is the quadratic formula
x+=+%281+%2B-+sqrt%28+%28-1%29%5E2-4%2A4%2A-5+%29%29%2F%282%2A4%29+
x+=+%281+%2B-+sqrt%28+1%2B80+%29%29%2F%288%29+
x+=+%281+%2B-+%289%29%29%2F%288%29+
two solutions are available
first:

x+=+%281+%2B+%289%29%29%2F%288%29+
x+=+5%2F4+
second:
x+=+%281+-+%289%29%29%2F%288%29+
x+=+-1+
