You can put this solution on YOUR website!
1/x^2 + 2/x - 35 = 0
x^2/x^2 + 2x^2/x - 35x^2 = 0
1 + 2x - 35x^2 = 0
x+=+%28-b+%2B-+sqrt%28+b%5E2+-+4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%28-2+%2B-+sqrt%28+4+%2B+140+%29%29%2F%282%2A-35%29+
x+=+%28-2+%2B-+sqrt%28+144+%29%29%2F%28-70%29+
x+=+%28-2+%2B-+12%29%2F%28-70%29+
x = 1/5 and x = -1/7 are your answers
