5x^2+2x-1=0 using the quadratic equation we get
x=(-b+-sqrt[b^2-4ac])/2a
x=(-2+-sqrt[4-4*5*-1])/2*5
x=(-2+-sqrt[4+20])/10
x=(-2+-sqrt24)/10
x=(-2+-4.9)/10
x=(-2+4.9/10
x=2.9/10
x=.29 solution
x=(-2-4.9)/10
x=-6.9/10
x=-.69 solution

Solve:
5x%5E2%2B2x-1+=+0 Use the quadratic formula: x+=+%28-b%2B-sqrt%28b%5E2-4ac%29%29%2F2a
x+=+%28-2%2B-sqrt%282%5E2-4%285%29%28-1%29%29%29%2F2%285%29
x+=+%28-2%2B-sqrt%284%2B20%29%29%2F10
x+=+%28-2%2B-sqrt%2824%29%29%2F10
x+=+%28-2%2B2sqrt%286%29%29%2F10 Simplify this to: x+=+%28-1%2Bsqrt%286%29%29%2F5
x+=+%28-2-2sqrt%286%29%29%2F10 Simplify this to: x+=+%28-1-sqrt%286%29%29%2F5
