Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify.</em>
y = x² + 8x
<u>Step 2: Find Roots</u>
- [Quadratic] Factor: y = x(x + 8)
- [Quadratic] Set up [Solve]: 0 = x(x + 8)
- [Quadratic] Define: x = 0, -8
∴ the roots of the quadratic equation y = x² + 8x is equal to 0 and -8.

Answer:
d. 2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
45a−25+7a=79
45a+−25+7a=79
(45a+7a)+(−25)=79(Combine Like Terms)
52a+−25=79
52a−25=79
Step 2: Add 25 to both sides.
52a−25+25=79+25
52a=104
Step 3: Divide both sides by 52.
52a
52
=
104
