Question 33

Jacob incorrectly factored 5x2 - 11x + 2 using the following steps:
Step 1: 5x2 + (-10x -x) + 2
Step 2: (5x2 - 10x)+(x - 2)
Step 3: 5x (x - 2) + 1(x - 2)
Step 4: (5x + 1)(x - 2)
In which step did he make his first error?

1 answer

Jacob made his first error in Step 2 when he broke up -11x into -10x and -x instead of -5x and -6x.
