Solve the equation: g(x)= 3 for x if g(x)=-.6x^2 + x + 4

You can put this solution on YOUR website!
-.6x%5E2+%2B+x+%2B+4=3
-.6x%5E2+%2B+x+%2B+1=0
Use the quadratic equation,
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%28-1+%2B-+sqrt%28+1%5E2-4%2A%28-0.6%29%2A%281%29+%29%29%2F%282%2A%28-0.6%29%29+
x+=+%28-1+%2B-+sqrt%28+1%2B2.4+%29%29%2F%28-1.2%29%29+
x+=+%28-1+%2B-+sqrt%28+3.4+%29%29%2F%28-1.2%29%29+
