x^2+6x-5
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%28-6+%2B-+sqrt%28+56+%29%29%2F%282%29+
x+=+%28-6+%2B-+sqrt%28+4%2A14+%29%29%2F%282%29+
x+=+%28-6+%2B-+2sqrt%28+14+%29%29%2F%282%29+
x+=+%28-3+%2B-+sqrt%28+14+%29%29+
radical format:
x is -3 -√14 , -3 + √14
Decimal Format: √14 = 3.7417 rounded
x is -6.7417, .7417
