Question

Factor the expression using GCF.

$9-5x$

Answer 1

Step 1: Given expression is = $9-5x$

We will now find the G.C.F of $\left(9\right),\left(15x\right)$ is

$$\begin{gathered} 9=3\times 3 \\ 15x=3\times 5\times x \end{gathered}$$

The common prime factor is $3$

The G.C.F of $\left(9\right),\left(15x\right)$ is $3$

Using the GCF to factor the expression

$$\begin{gathered} 9-15x=3\left(3\right)-3\left(5x\right)\{Rewritetheexpression\} \\ =3(3-5x)\{Distributiveproperty\} \end{gathered}$$

Hence, the required answer is $3(3-5x)$.
