Lesson 8: Strategizing to solve quadratic equationsStrategy in solving quadratics
Problem
Esma and Hunter were trying to solve the equation:
They both agreed they should first subtract and add to both sides and rewrite the equation as .
Then Esma said, "I can complete the square. I can add to both sides to rewrite this equation as , factor, and solve using square roots."
Hunter said, “I'll factor the left-hand side of the equation as and solve using the zero product property.”
Whose solution strategy would work?
