Answer 2

Answer:

(x + 2) (x + 4)

Explanation:

Before looking at my explanation make sure next time you are going to ask another question write the numbers that include exponents like this: x^2 instead of x2

Factor out x^2:

x + x

Factor out 6x:

Since it is in the bx form we’ll need two numbers be add so it can be equivalent to 6x

Answer: 4 and 2

Factor out 8:

4 x 2

Now start with the 8 and 6x

(? + 4) + (? + 2)

Then finish it off with x

(x + 4) (x + 2)
