You can put this solution on YOUR website!
2x%5E2%2B3x-5=0
if you compare this to standard formula ax%5E2%2Bbx%2Bc=0, you see that a=2, b=3, and c=-5
plug it in
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%28-3+%2B-+sqrt%28+3%5E2-4%2A2%2A%28-5%29+%29%29%2F%282%2A2%29+
x+=+%28-3+%2B-+sqrt%28+9%2B40+%29%29%2F4+
x+=+%28-3+%2B-+sqrt%28+49+%29%29%2F4+
x+=+%28-3+%2B-+7%29%2F4+
solutions:
x+=+%28-3+%2B+7%29%2F4+=>x+=+4%2F4+=>highlight%28x+=1%29
or
x+=+%28-3+-+7%29%2F4+=>x+=+-10%2F4+=>highlight%28x+=-5%2F2%29
