Question

Factor out the coefficient of the variable term.

$4x-20$

Answer 1

Factor out the coefficient

We have,

$$\begin{gathered} 4x-20 \\ =(4\times x)-(4\times 5) \\ =4(x-5)[\mathrm{Using}\mathrm{distributive}\mathrm{property}\mathrm{i}.\mathrm{e}.\left(\mathrm{ab}-\mathrm{ac}\right)=\mathrm{a}\left(\mathrm{b}-\mathrm{c}\right)] \end{gathered}$$

Hence, $4x-20=4(x-5)$.
