Q. Divide. Write your answer in simplest form.g2−12g−3÷2g+3g2
Rewrite as Multiplication: Rewrite the division problem as a multiplication problem by taking the reciprocal of the second fraction.(2g−3)/(g2−1)÷(g2)/(2g+3) can be rewritten as (2g−3)/(g2−1)×(2g+3)/g2.
Factor Denominator: Factor the denominator of the first fraction if possible.The denominator g2−1 is a difference of squares and can be factored into (g−1)(g+1).So, the expression becomes (2g−3)/((g−1)(g+1))×(2g+3)/g2.
Multiply Numerators and Denominators: Multiply the numerators and the denominators of the two fractions.The expression becomes (g−1)(g+1)∗g2(2g−3)∗(2g+3).
Expand Numerator: Expand the numerator of the resulting fraction.The numerator (2g−3)∗(2g+3) is a product of two binomials that are conjugates of each other, which results in a difference of squares.So, (2g−3)∗(2g+3)=(2g)2−(3)2=4g2−9.The expression becomes (4g2−9)/((g−1)(g+1)∗g2).
Simplify Expression: Simplify the expression by canceling out common factors if there are any.There are no common factors between the numerator 4g2−9 and the denominator (g−1)(g+1)⋅g2.So, the expression remains (4g2−9)/((g−1)(g+1)⋅g2).
Rewrite Denominator: Rewrite the denominator to make it clear what can be simplified.The denominator is (g−1)(g+1)×g2, which can be rewritten as g2(g−1)(g+1).The expression becomes g2(g−1)(g+1)4g2−9.
Cancel Common Term: Cancel out the common g2 term from the numerator and the denominator.After canceling out g2, the expression simplifies to (4−9/g2)/((g−1)(g+1)).
