MAFS.912.A-REI.1.1 NO CALCULATOR
Lisa solves a quadratic equation as shown.
Which of these best describes the error in Lisa’s work?
The last line should be 𝑥 = 2 or 𝑥 = 8.
The 6 should have been subtracted from both 6 and 𝑥2 + 2𝑥 − 8 before factoring.
Only (𝑥 + 4) or (𝑥 − 2) should be set equal to 6, not both factors.
The 6, 2, and −8 should be simplified to 3, 1, and −4 before factoring.
