Full solution

Q. Factor.\newline6j3+3j216j86j^3 + 3j^2 - 16j - 8
  1. Grouping for Factoring: Group the terms into two pairs to prepare for factoring by grouping. Group the first two terms and the last two terms separately. 6j3+3j216j86j^3 + 3j^2 - 16j - 8 can be grouped as (6j3+3j2)+(16j8)(6j^3 + 3j^2) + (-16j - 8).
  2. Factor out Common Factors: Factor out the greatest common factor from each group.\newlineFrom the first group 6j3+3j26j^3 + 3j^2, we can factor out 3j23j^2, which gives us 3j2(2j+1)3j^2(2j + 1).\newlineFrom the second group 16j8-16j - 8, we can factor out 8-8, which gives us 8(2j+1)-8(2j + 1).\newlineNow we have 3j2(2j+1)8(2j+1)3j^2(2j + 1) - 8(2j + 1).
  3. Factor out Binomial Factor: Factor out the common binomial factor from the two terms.\newlineBoth terms have a common factor of 2j+12j + 1, so we factor this out.\newlineThis gives us 2j+12j + 1(3j28)(3j^2 - 8).
  4. Check for Further Factoring: Check if the second factor (3j28)(3j^2 - 8) can be factored further.\newlineThe second factor is a difference of squares, as 88 is a perfect square (23)(2^3).\newlineHowever, 3j23j^2 is not a perfect square, so (3j28)(3j^2 - 8) cannot be factored further using real numbers.
