Full solution

Q. Factor.\newline3x36x2+8x163x^3 - 6x^2 + 8x - 16
  1. Identify common factors: Identify common factors in each term.\newlineWe look for any common factors in all terms of the polynomial 3x36x2+8x163x^3 - 6x^2 + 8x - 16.\newlineThe common factor here is 11, as there are no other common factors that divide all terms.
  2. Group terms to factor: Group terms to factor by grouping.\newlineWe can try to group the terms in pairs to see if we can factor by grouping.\newlineGroup the terms as follows: (3x36x2)+(8x16)(3x^3 - 6x^2) + (8x - 16).
  3. Factor out greatest common factor: Factor out the greatest common factor from each group.\newlineFrom the first group 3x36x23x^3 - 6x^2, we can factor out 3x23x^2, giving us 3x2(x2)3x^2(x - 2).\newlineFrom the second group 8x168x - 16, we can factor out 88, giving us 8(x2)8(x - 2).\newlineNow we have 3x2(x2)+8(x2)3x^2(x - 2) + 8(x - 2).
  4. Factor out common binomial factor: Factor out the common binomial factor.\newlineWe notice that (x2)(x - 2) is a common factor in both terms.\newlineFactor out (x2)(x - 2) to get (x2)(3x2+8)(x - 2)(3x^2 + 8).
  5. Check for further factorization: Check if the remaining quadratic can be factored further.\newlineThe quadratic 3x2+83x^2 + 8 does not have real roots and cannot be factored further over the real numbers.
