    Hello, Gayleayers! The answer is x (4x+1) (7x+5)

    Step-by-step explanation:

    To check your answer, use the box method or foil, whichever you prefer. When you use it, leave out the x in front of the parenthesis. The answer will come to x (28x^2+27x+5), then distribute the x. You will get your original answer.

    Have a great night and Happy New Year!

    Answer: x (7x + 5) (4x + 1)

    Step-by-step explanation:

    28x³ + 27x² + 5x

    = x (28x² + 27x + 5)

    = x (28x² + 7x + 20x + 5)

    = x[7x (4x + 1) + 5 (4x + 1) ]

    = x (7x + 5) (4x + 1)
