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


    (a+5) (a-4)=0

    or a=-5 ; +4

    both are factorised using splitting the middle term method
