Answer: SECOND OPTION
Step-by-step explanation:
Given the following equation:
![x^2-36=5x](https://tex.z-dn.net/?f=x%5E2-36%3D5x)
You can follow these steps in order to find the values of "x" that makes the equation true:
1. Subtract
from both sides of the equation:
![x^2-36-5x=5x-5x\\\\x^2-5x-36=0](https://tex.z-dn.net/?f=x%5E2-36-5x%3D5x-5x%5C%5C%5C%5Cx%5E2-5x-36%3D0)
2. Factor the equation. Find two numbers whose sum be -5 and whose product be -36. These are 4 and -9:
![(x+4)(x-9)=0](https://tex.z-dn.net/?f=%28x%2B4%29%28x-9%29%3D0)
Then you get:
![x_1=-4\\\\x_2=9](https://tex.z-dn.net/?f=x_1%3D-4%5C%5C%5C%5Cx_2%3D9)
Checking:
![(-4)^2-36=5(-4)\\\\-20=-20](https://tex.z-dn.net/?f=%28-4%29%5E2-36%3D5%28-4%29%5C%5C%5C%5C-20%3D-20)
TRUE
TRUE
If the difference is a constant, the difference is : (60-18)/(11-4)=42/7=6
