Question

X^2 + 9x + 14 I need help !

Answer 1

( + 2 ) (x+7 )

Explanation:

Use the sum-product pattern 2 + 9 + 1 4 2 + 7 + 2 + 1 4 2

Common factor from the two pairs 2 + 7 + 2 + 1 4 ( + 7 ) + 2 ( + 7 ) 3

Rewrite in factored form ( + 7 ) + 2 ( + 7 ) ( + 2 ) ( + 7 )

Answer 2

x² + 9x + 14 can be factored as (x+2)(x+7)

Explanation:

The general form is ax² + bx + c. If a=1, then you can start looking for two numbers that multiplied give c and added give b.

14 = 2*7

and

9 = 2+7

hence the easy factorization

(x+2)(x+7)

Keep in mind that it only works if a=1.
