Michaela and Grace were trying to solve the equation: 4 x 2 − 100 = 0 4x 2 −100=04, x, squared, minus, 100, equals, 0 Michaela said, “I'll factor the left-hand side of the equation as ( 2 x + 10 ) ( 2 x − 10 ) (2x+10)(2x−10)left parenthesis, 2, x, plus, 10, right parenthesis, left parenthesis, 2, x, minus, 10, right parenthesis and solve using the zero product property.” Grace said, “I'll isolate the x 2 x 2 x, squared term by adding 100 100100 and dividing by 4 44 on both sides of the equation. Then I'll solve by taking the square root.” Whose solution strategy would work?
