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

When using the Quadratic Formula, the value of the expression inside of the radical determines if the solutions are real or non-real.

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