Use the Discriminant to Determine Whether the Equation Has Two $\text { one real solution with a multiplicity of two }$

Multiple Choice

Use the discriminant to determine whether the equation has two non real complex solutions, one real solution with a multiplicity of two, or two real solutions. Match each of the equations with the number of decisions to obtain a true statement.
- $\text { one real solution with a multiplicity of two }$

A) $x ^ { 2 } + 10 x - 24 = 0$
B) $4 x ^ { 2 } + 12 x + 9 = 0$
C) $4 x ^ { 2 } - x + 9 = 0$
