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 $3(2x^2+x+7)$.
