You can put this solution on YOUR website!

3x%5E2%2B5x-1=0
as you can see, coefficients are: a=3,b=5, and c=-1

x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%28-5+%2B-+sqrt%28+5%5E2-4%2A3%2A%28-1%29+%29%29%2F%282%2A3%29+
x+=+%28-5+%2B-+sqrt%28+25%2B12+%29%29%2F6+
x+=+%28-5+%2B-+sqrt%28+37+%29%29%2F6+
x+=+%281%2F6%29%28-5+%2B-+sqrt%28+37+%29%29+
exact solutions:
x+=+%281%2F6%29%28-5+%2B+sqrt%28+37+%29%29+
or
x+=+%281%2F6%29%28-5+-+sqrt%28+37+%29%29+

or, approximate solutions:
x+=+%281%2F6%29%28-5+%2B+sqrt%28+37+%29%29+=>x+=0.18+
or
x+=+%281%2F6%29%28-5+-+sqrt%28+37+%29%29+ =>x+=1.85
