Hello there!

2x² + 8x = x² - 16

Let start by subtracting x² - 16 on both sides

2x² + 8x - x² - 16 = x² - 16 - x² - 16

x² + 8x - 16 = 0

Now we can factorize the left side

(x + 4)(x + 4) = 0

Set factors equal to 0

x + 4 = 0 or x + 4 = 0

x = 0 - 4 or x = 0 - 4

x = -4

Thus,

The only solution is -4

As always, it is my pleasure to help students like you!
