Do you mean:
x^2 - 2x - 13 = 0?
(x^2 = x squared.)
If you have typed your equation correctly, I don't see any solution.
To factor, you would want to find numbers that would give you a product of -13. One would have to be negative and the other positive to give you a negative value. However, 13 is a prime number, so the only choices are 1 and 13. They would not give you -2 for your middle term.
However, if your equation was:
X^2 - 12x - 13 = 0
Then it would factor into:
(x-13)(x+1) = 0
Giving you the answers of x = 13 or -1.
(It helps to type your information correctly.)
