Question

What number fills in the blank to complete the factorization of 3x + 24?

(x + 8)

Answer 1

There should be a 3 before the bracket

Answer 2

we have

`3x+24`

Find the greatest common factor GCF

we know that

`3\\ Factors=1,3\\ \\ 24=2^(3)*3\\ Factors=1,2,3,4,6,8,12,24`

so

The GCF is equal to
`3`

therefore

`3x+24=3*(x+8)`

the answer is

The number is
`3`
