Step-by-step explanation:

Step 1: Define

Identify.

y = x² + 8x

Step 2: Find Roots

1. [Quadratic] Factor:                                                                                          y = x(x + 8)
2. [Quadratic] Set up [Solve]:                                                                             0 = x(x + 8)
3. [Quadratic] Define:                                                                                         x = 0, -8

∴ the roots of the quadratic equation y = x² + 8x is equal to 0 and -8.
