You don' need to grooup
what you do is
factor first term
2=1 times 2
(2x-)(x-)
they are both minus since middle term is negative
now factor other term and get the factors closest together
20=5 times 4
(2x-5)(x-4)
try it out
2x^2-5x-8x+20
2x^2-13x+20
faotred is
(2x-5)(x-4)
if you want to group you do
2 times 20=40
find what 2 numbers multiply to get 40 and add to get -13
numbers are -8 and -5
split it up
2x^2-8x-5x+20
group like factors
(2x^2-8x)+(-5x+20)
undistribute common factors
(2x)(x-4)+(-5)(x-4)
reverse distributive property ab+ac=a(b+c)
(2x-5)(x-4)
