## Homework Statement

Hello!

One of the easiest rules (when possible to apply) to factor a quadratic is to find both x-s by

x1 + x2 = b

x1 * x2 = c

## Homework Equations

Please, take a look at what is written in the book. I can't grasp why x1 = -2 and x2 = 3, and not, as I thought, x1 = -3 and x2 = 2.

## The Attempt at a Solution

What is wrong in my understanding?

x1 + x2 = -1

x1 * x2 = -6

Therefore, x1 = -3 and x2 = 2; and the equation (x + 3 )(x - 2) =0

I would be grateful for the help.

Thank you!
