Problem

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 x2+6x+8=0.
Then Esma said, "I can complete the square. I can add 1 to both sides to rewrite this equation as x2+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?
