Michaela and Grace were trying to solve the equation:
4x^2 - 100 = 0
Michaela said, "I'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 x? 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 would work ?
