You are given the equation $5x^{2} + bx + 20 = 0$. For what values of $b$ does this equation have real solutions?   Homework Help ✎

The equation will have real solutions as long as the discriminant (the value under the radical) is greater than or equal to zero.

Solve the inequality $b^{2} − 4ac ≥ 0$ using the values for $a$ and $c$ in the given equation.
