How do I factor this polynomial by grouping?
2x^2 - 13x + 20


= (2x-5) (x-4)

I hope that’s help !

You don’ need to grooup
what you do is
factor first term
2=1 times 2
they are both minus since middle term is negative
now factor other term and get the factors closest together
20=5 times 4
try it out
faotred is
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
group like factors
undistribute common factors
reverse distributive property ab+ac=a(b+c)
