Factor x²+x-42

First, think of two numbers such that
- If we multiply them we'll get -42
- If we add them we'll get 1
These numbers are:-
7 and -6
Write them here:-
(x+7)(x-6)
<em>Note:-</em>
We don't have to use the Big X method, since the coefficient of x² is 1.
If it's greater than 1, like 2, then the Big X method comes in handy.
<h3>Good luck.</h3>
