Use the quadratic formula to solve 2x%5E2%2B11x-4
a=2 b=11 c=-4 (they are your coefficients)
so you would plug a b c in this formula
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
so we have
x+=+%28-11+%2B-+sqrt%28+11%5E2-4%2A2%2A%28-4%29+%29%29%2F%282%2A2%29+
x+=+%28-11+%2B-+sqrt%28+121%2B32+%29%29%2F%284%29+
x+=+%28-11+%2B-+sqrt%28+153+%29%29%2F%284%29+
x+=+%28-11+%2B-+3%2A%28sqrt%28+17+%29%29%29%2F%284%29+
