How to solve

x2-2x-13=0

Answers

Answered by PsyDAG
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.)
