Q. Multiply. Write your answer in simplest form.\newlineg+4g4×g2+7g+62g\frac{g + 4}{g - 4} \times \frac{g^2 + 7g + 6}{2g}
  1. Identify expressions to multiply: Identify the expressions to be multiplied.\newlineWe have two fractions to multiply: (g+4)/(g4)(g + 4)/(g - 4) and (g2+7g+6)/(2g)(g^2 + 7g + 6)/(2g).
  2. Factor second numerator: Factor the second numerator if possible.\newlineThe second numerator is a quadratic expression: g2+7g+6g^2 + 7g + 6.\newlineWe look for two numbers that multiply to 66 and add to 77. These numbers are 66 and 11.\newlineSo, g2+7g+6g^2 + 7g + 6 can be factored as (g+6)(g+1)(g + 6)(g + 1).
  3. Write multiplication of fractions: Write the multiplication of the two fractions with the factored numerator.\newlineThe expression becomes: (g+4g4)×(g+6)(g+1)2g(\frac{g + 4}{g - 4}) \times \frac{(g + 6)(g + 1)}{2g}.
  4. Multiply numerators and denominators: Multiply the numerators and the denominators.\newlineWhen multiplying fractions, we multiply the numerators together and the denominators together.\newlineThe expression becomes: (g+4)(g+6)(g+1)(g4)2g.\frac{(g + 4) \cdot (g + 6) \cdot (g + 1)}{(g - 4) \cdot 2g}.
  5. Simplify expression if possible: Simplify the expression if possible.\newlineWe look for common factors in the numerator and the denominator that can be canceled out.\newlineThere are no common factors between the numerator and the denominator.
  6. Expand numerators if necessary: Expand the numerators if necessary to check for any simplification.\newlineMultiplying out the numerators gives us: (g+4)×(g+6)×(g+1)=(g2+10g+24)×(g+1)(g + 4) \times (g + 6) \times (g + 1) = (g^2 + 10g + 24) \times (g + 1).\newlineExpanding this gives us: g3+10g2+24g+g2+10g+24=g3+11g2+34g+24g^3 + 10g^2 + 24g + g^2 + 10g + 24 = g^3 + 11g^2 + 34g + 24.
  7. Write final expression: Write the final expression.\newlineThe final expression is: (g3+11g2+34g+24)/(2g(g4))(g^3 + 11g^2 + 34g + 24) / (2g(g - 4)).
  8. Check for further simplification: Check if the final expression can be simplified further. There are no common factors between the numerator and the denominator that can be canceled out.
