Esma and Hunter were trying to solve the equation:
x2 + 8x = 2x - 8
They both agreed they should first subtract 2x and add 8 to both sides and rewrite the equation as
22 + 6x + 8 = 0.
Then Esma said, "I can complete the square. I can add 1 to both sides to rewrite this equation as
22 + 6x + 9 = 1, factor, and solve using square roots."
Hunter said, “I'll factor the left-hand side of the equation as (x + 2)(x + 4) and solve using the zero
product property."
Whose solution strategy would work?
