Complete the square for x^2+12x-5.
Setler [38]

Answer:

x^2+12x-5=(x+6)^2-41

Step-by-step explanation:

The given expression is x^2+12x-5

Comparing to ax^2+bx+c, we have a=1,b=12,c=-5

We add and subtract (\frac{b}{2a})^2

x^2+12x+6^2-6^2-5

This implies that:

\boxed{x^2+6x+36}-36-5

The expression in the rectangle is a perfect square

(x+6)^2-41

Therefore x^2+12x-5=(x+6)^2-41
