Question

Part 1: Solve the following equation using one of the methods listed below.
Part 2: Using complete sentences, explain why you chose the method you used.

Equation:
0 = x2 + 10x + 5

Methods:
Completing the Square
Factoring
Quadratic Formula
Graphing

Answer 1

I choose "completing the square" method because it is not factorable, and the coefficient of x is a 1.

x^2 +10x +25=-5+25
(x+5)^2=20
\[x+5=\sqrt{20}=2\sqrt{5}\]
\[x=-5\pm2\sqrt{5}\]

Answer 2

typo I meant to say the coefficient of x^2 is a 1.
