Full solution

Q. Factor.\newline2g2+13g+112g^2 + 13g + 11
  1. Identify Coefficients: Identify the coefficients of the quadratic expression.\newlineThe quadratic expression is in the form of ag2+bg+ca g^2 + b g + c. For the given expression 2g2+13g+112g^2 + 13g + 11, we have:\newlinea=2a = 2, b=13b = 13, and c=11c = 11.
  2. Find Multiplying Numbers: Find two numbers that multiply to aca*c (which is 211=222*11 = 22) and add up to bb (which is 1313).\newlineWe need to find two numbers that when multiplied give us 2222 and when added give us 1313. The numbers that satisfy these conditions are 22 and 1111 because:\newline211=222 * 11 = 22 and 2+11=132 + 11 = 13.
  3. Rewrite Middle Term: Rewrite the middle term of the quadratic expression using the two numbers found in the previous step.\newlineWe can express the middle term 13g13g as the sum of 2g2g and 11g11g. Therefore, we rewrite the expression as:\newline2g2+2g+11g+112g^2 + 2g + 11g + 11.
  4. Factor by Grouping: Factor by grouping.\newlineWe group the terms as follows: 2g2+2g2g^2 + 2g + 11g+1111g + 11.\newlineNow we factor out the common factors from each group:\newlineFrom the first group, we can factor out 2g2g: 2g(g+1)2g(g + 1).\newlineFrom the second group, we can factor out 1111: 11(g+1)11(g + 1).
  5. Write Factored Form: Write the factored form of the expression.\newlineSince both groups contain the common factor (g+1)(g + 1), we can factor it out:\newline2g(g+1)+11(g+1)=(2g+11)(g+1)2g(g + 1) + 11(g + 1) = (2g + 11)(g + 1).
