Question: ? Analyzing Student Work Mathieu is finding the x-intercepts of the function Which error did Mathieu make? f (2) = 202 + 4ac + 3.

Analyzing Student Work Mathieu is finding the x-intercepts of the function Which error did Mathieu make? f (2) = 202 + 4ac + 3. Mathieu's Work He did not use the constant as the x- 1. 0 = x2 + 4x + 3 intercept. 2. 0 = (2+ 3) (2+1) 3. x +3 =x+1 4. ac = 2 - 2 He incorrectly solved the equation 5.0 = -2 x + 3 = a+1. 6. There are no x-intercepts. He set the factored expressions equal to each other. He factored incorrectly
