Full solution

Q. Factor.\newline6u38u215u+206u^3 - 8u^2 - 15u + 20
  1. Identify Common Factor: Look for a common factor in all terms.\newlineCheck if there is a greatest common factor (GCF) that can be factored out from all terms of the polynomial 6u38u215u+206u^3 - 8u^2 - 15u + 20.\newlineThe GCF of 6u36u^3, 8u28u^2, 15u15u, and 2020 is 11, so there is no common factor other than 11.
  2. Grouping for Factoring: Group terms to facilitate factoring by grouping.\newlineWe can group the terms as follows: 6u38u26u^3 - 8u^2 and 15u+20 -15u + 20.\newlineNow we will look for common factors within each group.
  3. Factor Out from First Group: Factor out the common factor from the first group.\newlineIn the first group (6u38u2)(6u^3 - 8u^2), we can factor out 2u22u^2, which gives us 2u2(3u4)2u^2(3u - 4).
  4. Factor Out from Second Group: Factor out the common factor from the second group.\newlineIn the second group (15u+20)(-15u + 20), we can factor out 5-5, which gives us 5(3u4)-5(3u - 4).
  5. Write Factored Form: Write the factored form of the polynomial.\newlineWe now have 2u2(3u4)5(3u4)2u^2(3u - 4) - 5(3u - 4). Notice that (3u4)(3u - 4) is a common factor.\newlineWe can factor (3u4)(3u - 4) out of both terms, which gives us (3u4)(2u25)(3u - 4)(2u^2 - 5).
  6. Check Further Factoring: Check for any further factoring possibilities.\newlineThe terms 2u22u^2 and 5-5 do not have any common factors, and 2u252u^2 - 5 cannot be factored further over the integers.\newlineTherefore, the factored form of the polynomial is (3u4)(2u25)(3u - 4)(2u^2 - 5).
