Step 1: Find the greatest common factor (GCF) of the terms.
The GCF of 3d³, -12d², and -15d is 3d.
Step 2: Rewrite the expression using the GCF.
3d(d² - 4d - 5)
Step 3: Factor the quadratic expression in the parentheses.
The quadratic expression can be factored as (d - 5)(d + 1).
Step 4: Rewrite the expression using the factored form.
3d(d - 5)(d + 1)
Therefore, the factored form of 3d³ - 12d² - 15d is 3d(d - 5)(d + 1).
