How do you factor #4x^5 + 6x3 + 6x^2 + 9#?
Factor by grouping
Put parenthesis around two first and last terms
Factor out gcf
If you did it right the parenthesis should be same so you can cross one out and make a new parenthesis with the two terms you factored out
This is more concept than logic so don't mind the addition sign in between
