2k(1+5a) or 2k(5a+1)
[tex]\rightsquigarrow\circ\boldsymbol{Explanation.}\circ\leftharpoonup[/tex]
First of all, let's find the common term of this binomial (an expression with two terms; the prefix bi- means "two")
Note that both terms have 2k in them. So, we factor it out.
[tex]\twoheadrightarrow\sf 2k\div2k+10ak\div2k[/tex]
[tex]\bullet[/tex] Simplify
[tex]\twoheadrightarrow\sf 1+5a[/tex]
[tex]\bullet[/tex] 2k can't just vanish into thin air, so we put it outside the parentheses:
[tex]\twoheadrightarrow\sf 2k(1+5a)[/tex]
[tex]\bullet[/tex] Great job! We factored the expression successfully
