Quadratic Equations Practice Test

What are the solutions to the equation $x^2-5x-24=0$? Choose the pair of real solutions that makes the equation true. (Be careful: a common mistake is to factor using numbers that multiply to $24$ instead of $-24$.)​

Solve the equation $3x^2+2x-8=0$. Which pair gives all real solutions? Plausible wrong answers can come from a sign error in $-b\pm\sqrt{b^2-4ac}$ or an arithmetic error in the discriminant.
