Problem
LuAnn and Bobby took the same algebra test. Problem 5 asked them to find the solutions to a quadratic equation. LuAnn misread the constant term. She correctly found that the roots to her incorrect quadratic were −4 and 7. Bobby misread the linear term. He correctly found that the roots to his incorrect quadratic were −4 and 10. What are the roots of the correct quadratic?
