Question

Which step(s) are errors is it step 1 step 2 step 3 step4 or step 5?

Answer 1

Step 1

Explanation:

c is not -6. Because the equation equals 6, we will add 6 to both sides to set it equal to zero, which will make c=0

Answer 2

Step 1, and step 5

Explanation:

The end of the equation has to equal 0, so c can not be -6 but instead -12.

They forgot about the 4 +/- the square root of 40 in the last step.
