Reorder Terms in Descending Order: First, we should reorder the terms of the polynomial in descending powers of x. 36x2−81x−3x3 can be rewritten as −3x3+36x2−81x.
Factor Out GCF: Next, we can factor out the greatest common factor (GCF) from each term. The GCF here is −3x.Factoring out −3x gives us −3x(x2−12x+27).
Factor Quadratic Expression: Now we need to factor the quadratic expression x2−12x+27. We look for two numbers that multiply to 27 and add up to −12. These numbers are −3 and −9. So, we can write x2−12x+27 as (x−3)(x−9).
Combine Factors for Final Form: Finally, we combine the factored quadratic with the GCF we factored out earlier to get the completely factored form of the polynomial.The final factored form is −3x(x−3)(x−9).
