We're asked to factor this expression by grouping. Now, they mention grouping, we're going to see what grouping is, but we're going to see very quickly that we have to do this thing called …

Sal introduces the method of grouping, which is very useful in factoring quadratics whose leading coefficient is not 1. Created by Sal Khan and CK-12 Foundation.

Factor quadratics of the form ax²+bx+c.

If you only see the variable x^2, then there is an invisible coefficient of 1 in front which generally makes factoring easier if possible. So use coefficient as a number in front of a variable and …

After Sal factors out the 5 he goes through a process to factor by grouping, which is the point of the video. You can do the factoring by grouping without factoring out the 5 first, but it will be …
