Q. Multiply. Write your answer in simplest form.\newline2q+1q2×9q26q+13q+2\frac{2q + 1}{q^2} \times \frac{9q^2 - 6q + 1}{3q + 2}
  1. Identify Expressions: Identify the expressions to be multiplied.\newlineWe have two fractions to multiply: (2q+1)/q2(2q + 1)/q^2 and (9q26q+1)/(3q+2)(9q^2 - 6q + 1)/(3q + 2).
  2. Multiply Numerators and Denominators: Multiply the numerators and the denominators.\newlineThe product of the two fractions is (2q+1)(9q26q+1)/(q2)(3q+2)(2q + 1)(9q^2 - 6q + 1) / (q^2)(3q + 2).
  3. Perform Multiplication in Numerator: Perform the multiplication in the numerator.\newlineWe need to multiply the two binomials (2q+1)(2q + 1) and (9q26q+1)(9q^2 - 6q + 1) using the distributive property (FOIL method).\newline(2q+1)(9q26q+1)=2q(9q2)+2q(6q)+2q(1)+1(9q2)1(6q)+1(1)(2q + 1)(9q^2 - 6q + 1) = 2q(9q^2) + 2q(-6q) + 2q(1) + 1(9q^2) - 1(6q) + 1(1)\newline=18q312q2+2q+9q26q+1= 18q^3 - 12q^2 + 2q + 9q^2 - 6q + 1\newline=18q33q24q+1= 18q^3 - 3q^2 - 4q + 1
  4. Write Product as Single Fraction: Write the product as a single fraction.\newlineNow we have the numerator, we can write the product as a single fraction:\newline(18q33q24q+1)/(q2)(3q+2)(18q^3 - 3q^2 - 4q + 1) / (q^2)(3q + 2)
  5. Simplify Fraction: Simplify the fraction if possible.\newlineLooking at the numerator and the denominator, there are no common factors that can be canceled out. Therefore, the fraction is already in its simplest form.
