This is Adele's solution for the equation x^2 + 8x - 9 = 0 Step 1 x^2 + 8x - 9 = 0 Step 2 x^2 + 8x = 9 Step 3 ( x + 4 )^2 = 25 S tep 4 x + 4 = 25 or x + 4 = - 25 Step 5 x = 21 or x = - 29. Where did Adele make her mistake. Show all of your work.

<h3><em>
The mistake was in step 1. Here is how to correctly solve the equation:
</em></h3><h3><em>
x² - 8x – 33 = 0
</em></h3><h3><em>
(x - 11) (x + 3) = 0
</em></h3><h3><em>
x – 11 = 0
</em></h3><h3><em>
x +3 = 0
</em></h3><h3><em>
x = 11 and x = -3 </em>
