Q. Divide. Write your answer in simplest form.\newline2g3g21÷g22g+3\frac{2g - 3}{g^2 - 1} \div \frac{g^2}{2g + 3}
  1. Rewrite as Multiplication: Rewrite the division problem as a multiplication problem by taking the reciprocal of the second fraction.\newline(2g3)/(g21)÷(g2)/(2g+3)(2g - 3)/(g^2 - 1) \div (g^2)/(2g + 3) can be rewritten as (2g3)/(g21)×(2g+3)/g2(2g - 3)/(g^2 - 1) \times (2g + 3)/g^2.
  2. Factor Denominator: Factor the denominator of the first fraction if possible.\newlineThe denominator g21g^2 - 1 is a difference of squares and can be factored into (g1)(g+1)(g - 1)(g + 1).\newlineSo, the expression becomes (2g3)/((g1)(g+1))×(2g+3)/g2(2g - 3)/((g - 1)(g + 1)) \times (2g + 3)/g^2.
  3. Multiply Numerators and Denominators: Multiply the numerators and the denominators of the two fractions.\newlineThe expression becomes (2g3)(2g+3)(g1)(g+1)g2\frac{(2g - 3) * (2g + 3)}{(g - 1)(g + 1) * g^2}.
  4. Expand Numerator: Expand the numerator of the resulting fraction.\newlineThe numerator (2g3)(2g+3)(2g - 3) * (2g + 3) is a product of two binomials that are conjugates of each other, which results in a difference of squares.\newlineSo, (2g3)(2g+3)=(2g)2(3)2=4g29(2g - 3) * (2g + 3) = (2g)^2 - (3)^2 = 4g^2 - 9.\newlineThe expression becomes (4g29)/((g1)(g+1)g2)(4g^2 - 9)/((g - 1)(g + 1) * g^2).
  5. Simplify Expression: Simplify the expression by canceling out common factors if there are any.\newlineThere are no common factors between the numerator 4g294g^2 - 9 and the denominator (g1)(g+1)g2(g - 1)(g + 1) \cdot g^2.\newlineSo, the expression remains (4g29)/((g1)(g+1)g2)(4g^2 - 9)/((g - 1)(g + 1) \cdot g^2).
  6. Rewrite Denominator: Rewrite the denominator to make it clear what can be simplified.\newlineThe denominator is (g1)(g+1)×g2(g - 1)(g + 1) \times g^2, which can be rewritten as g2(g1)(g+1)g^2(g - 1)(g + 1).\newlineThe expression becomes 4g29g2(g1)(g+1)\frac{4g^2 - 9}{g^2(g - 1)(g + 1)}.
  7. Cancel Common Term: Cancel out the common g2g^2 term from the numerator and the denominator.\newlineAfter canceling out g2g^2, the expression simplifies to (49/g2)/((g1)(g+1))(4 - 9/g^2)/((g - 1)(g + 1)).
