    Answer:

    (4w – 5) (w – 4)

    Step-by-step explanation:

    4w² – 21w + 20

    We will look two numbers that when we add will give is -21 and when we multiply will give us 20 × 4= 80 and these numbers are -16 and -5.

    4w² – 16w – 5w + 20

    4w(w – 4) – 5(w – 4)

    (4w – 5) (w – 4)
