Answer: Option C
Step-by-step explanation:
Given the quadratic equation
, substitute
:
![0 = x^2 - 13x](https://tex.z-dn.net/?f=0%20%3D%20x%5E2%20-%2013x)
In this case, to find the solutions of the given quadratic equation, you must factor out the variable "x". Then:
![0=x(x-13)](https://tex.z-dn.net/?f=0%3Dx%28x-13%29)
Therefore, you get that the solutions of this equation are the following:
![x=0\\\\\\x-13=0\\x=13](https://tex.z-dn.net/?f=x%3D0%5C%5C%5C%5C%5C%5Cx-13%3D0%5C%5Cx%3D13)
Then, the answer is:
This matches with the option C.
