Michaela and Grace were trying to solve the equation: 4x2 – 100 = 0
Michaela said, "T'll factor the left-hand side of the
equation as (2x + 10)(2x – 10) and solve using the
zero product property."
Grace said, “I'll isolate the x2 term by adding 100 and
dividing by 4 on both sides of the equation. Then I'll
solve by taking the square root."
Whose solution strategy would work?
