Full solution

Q. Factor the trinomial:\newline5x2+11x+6 5 x^{2}+11 x+6 \newlineAnswer:
  1. Identify Structure: Identify the structure of the trinomial.\newlineThe trinomial is in the form ax2+bx+cax^2 + bx + c, where a=5a = 5, b=11b = 11, and c=6c = 6.
  2. Find Multiplying Numbers: Look for two numbers that multiply to acac (5×6=305 \times 6 = 30) and add up to bb (1111).\newlineWe need to find two numbers that multiply to 3030 and add up to 1111. The numbers 55 and 66 fit this requirement because 5×6=305 \times 6 = 30 and 5+6=115 + 6 = 11.
  3. Rewrite Middle Term: Rewrite the middle term 11x11x using the two numbers found in Step 22.\newlineThe trinomial 5x2+11x+65x^2 + 11x + 6 can be rewritten as 5x2+5x+6x+65x^2 + 5x + 6x + 6.
  4. Factor by Grouping: Factor by grouping.\newlineGroup the terms into two pairs: (5x2+5x)(5x^2 + 5x) and (6x+6)(6x + 6).
  5. Factor out Common Factor: Factor out the greatest common factor from each group.\newlineFrom the first group 5x2+5x5x^2 + 5x, factor out 5x5x to get 5x(x+1)5x(x + 1).\newlineFrom the second group 6x+66x + 6, factor out 66 to get 6(x+1)6(x + 1).
  6. Write Final Factored Form: Write down the final factored form.\newlineSince both groups contain the common factor (x+1)(x + 1), the trinomial can be factored as (5x+6)(x+1)(5x + 6)(x + 1).
