    Answer:

    (x + 2) (x + 4)

    Step-by-step 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)
