Question

Factor by gcf 6x2+3x+21 The 2 is supposed to be small.

Answer 1

Given:

The expression is:

`6x^2+3x+21`

To find:

The factor of the given expression by GCF.

Solution:

We have,

`6x^2+3x+21`

Here, 3 is the greatest common factor (GCF) of
`6x^2,3x,21`.

Taking out GCF, we get

`6x^2+3x+21=3(2x^2+x+7)`

Therefore, the required factor form of the given expression is
`3(2x^2+x+7)`.
