For this case we have the following xpresion:


2y ^ 2 + 3y + 4y + 6

We can rewrite it as:


2y ^ 2 + 7y + 6

Where:


a = 2\\b = 7\\c = 6\\

We must factor, for this we follow the steps below:

Step 1:

The term of the medium must be rewritten as the sum of two terms, whose sum is 7 and the product is
a.c = 2 * (6) = 12:

Then, the term of the medium, fulfilling the two previous conditions, can be written as:


4y + 3y

We check:


4 * 3 = 12\\4 + 3 = 7

So, we have:


2y ^ 2 + 4y + 3y + 6

Step 2:

The maximum common denominator (the largest integer that divides them without leaving residue) of each group is factored


2y ^ 2 + 4y + 3y + 6\\2y (y + 2) + 3 * (y + 2)

Step 3:

We take common factor
(y + 2):


(y + 2) (2y + 3)

Thus, the expression
2y ^ 2 + 3y + 4y + 6 can be factored as:


(y + 2) (2y + 3)

Answer:


(y + 2) (2y + 3)
