Full solution

Q. Factor.\newline14r310r27r+514r^3 - 10r^2 - 7r + 5
  1. Look for Common Factor: Look for a common factor in all terms.\newlineCheck if there is a common factor that can be factored out from all terms in the polynomial 14r310r27r+514r^3 - 10r^2 - 7r + 5.\newlineThere is no common factor other than 11.
  2. Group Terms for Factoring: Group terms to facilitate factoring by grouping. Group the terms into two pairs: (14r310r2)(14r^3 - 10r^2) and (7r+5)(-7r + 5).
  3. Factor Out Common Factor: Factor out the greatest common factor from each group.\newlineFrom the first group 14r310r214r^3 - 10r^2, factor out 2r22r^2, which gives us 2r2(7r5)2r^2(7r - 5).\newlineFrom the second group 7r+5-7r + 5, we can factor out 1-1, which gives us 1(7r5)-1(7r - 5).
  4. Write Factored Groups: Write the expression with the factored groups.\newlineNow we have 2r2(7r5)1(7r5)2r^2(7r - 5) - 1(7r - 5).
  5. Factor Out Common Binomial: Factor out the common binomial factor.\newlineThe common binomial factor is (7r5)(7r - 5). Factor this out from the expression.\newlineThis gives us (7r5)(2r21)(7r - 5)(2r^2 - 1).
  6. Check Quadratic Factor: Check if the quadratic factor can be factored further.\newlineThe quadratic factor 2r212r^2 - 1 is a difference of squares and can be factored as (2r1)(2r+1)(\sqrt{2}r - 1)(\sqrt{2}r + 1).
  7. Write Final Factored Form: Write the final factored form of the polynomial.\newlineThe final factored form of the polynomial is (7r5)(2r1)(2r+1)(7r - 5)(\sqrt{2}r - 1)(\sqrt{2}r + 1).
