Full solution

Q. Find the quadratic polynomial that completes the factorization. \newlinew3+125=(w+5)(_____)w^3 + 125 = (w + 5)(\_\_\_\_\_)
  1. Factorize sum of cubes: We know that w3+125w^3 + 125 is a sum of cubes, which factors as (w+5)(w25w+25)(w + 5)(w^2 - 5w + 25).
  2. Expand factorized expression: To check, we can expand (w+5)(w25w+25)(w + 5)(w^2 - 5w + 25) to see if it equals w3+125w^3 + 125.(w+5)(w25w+25)=w35w2+25w+5w225w+125(w + 5)(w^2 - 5w + 25) = w^3 - 5w^2 + 25w + 5w^2 - 25w + 125.
  3. Simplify the expression: Simplify the expression: w35w2+25w+5w225w+125=w3+125w^3 - 5w^2 + 25w + 5w^2 - 25w + 125 = w^3 + 125.
