Can anyone help me understand how to do this?
Factoring each polynomial
solve each equation
I am so lost with this one I can not grab how you get a number from this.
thanks for trying who ever you may be
splitting the middle term as
take common factor from 2 terms,sequentially as
(X+2a) (X+3a) answer is x=-2a ;X=-3a
Question 2: a^2+a-20=0
or a=-5 ; +4
both are factorised using splitting the middle term method
