Answer:
x = -1.14 or -13.14
Explanations:
The given equation is:
![x^2+12x\text{ = 15}](https://tex.z-dn.net/?f=x%5E2%2B12x%5Ctext%7B%20%20%3D%20%2015%7D)
Find the half of 12, and add the square to both sides of the equation.
That is add 6² to both sides
![x^2+12x\text{ + 6}^{2}\text{ = 15 + 6}^{2}](https://tex.z-dn.net/?f=x%5E2%2B12x%5Ctext%7B%20%2B%206%7D%5E%7B2%7D%5Ctext%7B%20%20%3D%20%2015%20%2B%206%7D%5E%7B2%7D)
![\begin{gathered} (x+6)^2\text{ = 15 + 3}6 \\ (x+6)^2\text{ = 51} \\ \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%28x%2B6%29%5E2%5Ctext%7B%20%3D%20%2015%20%20%2B%20%203%7D6%20%5C%5C%20%28x%2B6%29%5E2%5Ctext%7B%20%3D%2051%7D%20%5C%5C%20%20%5Cend%7Bgathered%7D)
Find the square root of both sides:
![\begin{gathered} \sqrt[]{(x+6)^2_{}}=\pm\sqrt[]{51} \\ \text{x + 6 = }\pm\sqrt[]{51} \\ x\text{ = -6 }\pm\sqrt[]{51} \\ \text{x = }-6\pm7.14 \\ x\text{ = -6+7.14 = }1.14 \\ x\text{ = -6 - 7.14} \\ \text{x = -13.14} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Csqrt%5B%5D%7B%28x%2B6%29%5E2_%7B%7D%7D%3D%5Cpm%5Csqrt%5B%5D%7B51%7D%20%5C%5C%20%5Ctext%7Bx%20%20%2B%20%206%20%20%3D%20%7D%5Cpm%5Csqrt%5B%5D%7B51%7D%20%5C%5C%20x%5Ctext%7B%20%20%3D%20%20-6%20%20%7D%5Cpm%5Csqrt%5B%5D%7B51%7D%20%5C%5C%20%5Ctext%7Bx%20%20%3D%20%7D-6%5Cpm7.14%20%5C%5C%20x%5Ctext%7B%20%20%3D%20-6%2B7.14%20%20%3D%20%7D1.14%20%5C%5C%20x%5Ctext%7B%20%3D%20-6%20-%207.14%7D%20%5C%5C%20%5Ctext%7Bx%20%3D%20-13.14%7D%20%5Cend%7Bgathered%7D)
