Question

Greatest Common Factor.Factor the expression completely.−18+15x

Answer 1

`-18+15x=3(5x-6)`

Step-by-step explanation:

To factor, we need to find a common factor between the two terms. Since x in only one term, is not a common factor. Let's see the divisors of 15 and 18:

`\begin{gathered} 15:1,3,5,15 \\ 18:1,2,3,6,9,18 \end{gathered}`

The only common divisor is 3. then:

`\begin{gathered} -18=3(-6) \\ 15x=3(5x) \end{gathered}`

Thus,

`-18+15x=3(5x-6)`
