Question

Use the grouping method to factor this polynomial.
3+2x2 +7 x + 14

Answer 1

7 ( x + 3 )

Explanation:

Use order of operations to multiply first.

3+2x2 +7 x + 14

3+4 +7 x + 14

Now group like terms.

3+ 7x + 4 + 14

Add like terms

7x + 21

Find the two multiples of 21.

7x + 7 x 3

Now factor out the 7.

7( x + 3 )
