Answer: Option C

Explanation:

Given the quadratic equation
y = x^2 - 13x, substitute
y=0:


0 = x^2 - 13x

In this case, to find the solutions of the given quadratic equation, you must factor out the variable "x". Then:


0=x(x-13)

Therefore, you get that the solutions of this equation are the following:


x=0\\\\\\x-13=0\\x=13

Then, the answer is:


x = 0\ or\ x = 13

This matches with the option C.
