It's a quadratic equation and the x^2 is x squared

The goal here is to solve for the unknown variable, **x**, when the equation is equal to zero. Since the equation is a 2nd degree polynomial function (or a quadratic function), we first want to change it into a product of two binomials by factoring.
Once we have done that, we can apply the zero product property to solve for x.

x^{2} - 4x - 5 = 0

(x - 5)(x + 1) = 0

x - 5 = 0 and x + 1 = 0

**x = 5** **x = -1**
