Two terms that add to 22 and multiply to give 21 are 21 and 1. Replace 22x with 22x and x.
7x^2 + 21x + x + 3
7x (x + 3) + 1 (x + 3)
(7x + 1) (x + 3)

(2x )(x )
What are the factors of -15? -1*15 and -3*5, 3*-5 , 1*-15
We need 2* one factor ± the other factor = -7
2*-5 +3 = -7
That means the -5 is on the outside and the +3 is on the inside
(2x +3 )(x-5)
