2k(1+5a) or 2k(5a+1)

$\rightsquigarrow\circ\boldsymbol{Explanation.}\circ\leftharpoonup$

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.

$\twoheadrightarrow\sf 2k\div2k+10ak\div2k$

$\bullet$ Simplify

$\twoheadrightarrow\sf 1+5a$

$\bullet$ 2k can't just vanish into thin air, so we put it outside the parentheses:

$\twoheadrightarrow\sf 2k(1+5a)$

$\bullet$ Great job! We factored the expression successfully
