Full solution

Q. Factor.\newlines3+2s28s16s^3 + 2s^2 - 8s - 16
  1. Identify Common Factors: Look for common factors in pairs of terms.\newlineWe can group the terms to look for common factors in pairs. Let's group the first two terms and the last two terms separately.\newlineGroup 11: s3+2s2s^3 + 2s^2\newlineGroup 22: 8s16-8s - 16
  2. Factor Out GCF: Factor out the greatest common factor from each group.\newlineFrom Group 11, we can factor out an s2s^2:\newlines3+2s2=s2(s+2)s^3 + 2s^2 = s^2(s + 2)\newlineFrom Group 22, we can factor out a 8-8:\newline8s16=8(s+2)-8s - 16 = -8(s + 2)
  3. Write Factored Groups: Write the expression with the factored groups.\newlineNow we have:\newlines2(s+2)8(s+2)s^2(s + 2) - 8(s + 2)
  4. Factor Out Binomial Factor: Factor out the common binomial factor.\newlineWe can see that (s+2)(s + 2) is a common factor in both terms, so we factor it out:\newline(s28)(s+2)(s^2 - 8)(s + 2)
  5. Recognize Difference of Squares: Recognize that s28s^2 - 8 is a difference of squares.\newlines28s^2 - 8 can be factored further since it is a difference of squares:\newline$s^\(2\) - \(8\) = (s + \(2\)\sqrt{\(2\)})(s - \(2\)\sqrt{\(2\)})
  6. Write Final Factored Form: Write the final factored form.\(\newline\)Now we can write the polynomial in its completely factored form:\(\newline\)\((s + 2\sqrt{2})(s - 2\sqrt{2})(s + 2)\)
