You can put this solution on YOUR website!
3x^2 + 2x = 3
:
3x^2 + 2x - 3 = 0
:
You need to use the quadratic formula: x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
In this equation a=3; b=2; c=-3
x+=+%28-2+%2B-+sqrt%282%5E2+-+4+%2A+3+%2A+-3+%29%29%2F%282%2A3%29+
:
x+=+%28-2+%2B-+sqrt%284+-+%28-36%29+%29%29%2F%286%29+
:
x+=+%28-2+%2B-+sqrt%284+%2B+36+%29%29%2F%286%29+
:
x+=+%28-2+%2B-+sqrt%2840+%29%29%2F%286%29+
Two solutions:
x+=+%28-2+%2B+6.324555%29%2F%286%29+
x+=+%284.324555%29%2F%286%29+
x = +.72076
and
x+=+%28-2+-+6.324555%29%2F%286%29+
x+=+%28-8.324555%29%2F%286%29+
x = -1.3874

You can check both solutions in the original equation to confirm my answer
