A student performed the following steps to find the solution to the equation
x2 - 2x -8 -0. Where did the student go wrong?
Step 1. Factor the polynomial into (x-4) and (x - 2)
Step 2. x-4 = 0 and x - 2 = 0
Step 3. x = 4 and x = 2
Only the 2 is negative. The 2nd step is incorrect.
Step-by-step explanation:
In this equation, she did the 2nd step wrong because when you use the factors of 8, -4 and -2 just get you -6, not -2. So, you would have a -4 and a positive 2.
