Mathieu is finding the x-intercepts of the function
f (x) = x2 + 4x + 3. His work is shown below.
Which error did Mathieu make?
He factored incorrectly.
He did not use the constant as the x-intercept.
O He set the factored expressions equal to each
other.
1.0 = x2 + 4x + 3
2. 0 = (x + 3) (x + 1)
3. x + 3 = x + 1
4. X = X-2
5.0 = - 2
6. There are no x-intercepts.
O He incorrectly solved the equation x + 3 = x + 1.
