Q. Perform the following operation and express in simplest form.x2−9x2+11x+24÷x34x+32Answer:
Identify and Rewrite Division: Identify the given expression and rewrite the division as multiplication by the reciprocal of the second fraction.The expression is (x2+11x+24)/(x2−9)÷(4x+32)/(x3).Rewrite as (x2+11x+24)/(x2−9)×(x3)/(4x+32).
Factor Numerators and Denominators: Factor the numerator and denominator of the first fraction and the numerator of the second fraction.The numerator x2+11x+24 can be factored into (x+8)(x+3).The denominator x2−9 is a difference of squares and can be factored into (x+3)(x−3).The numerator 4x+32 of the second fraction can be factored out by 4 to get 4(x+8).The expression becomes (x+3)(x−3)(x+8)(x+3)×4(x+8)x3.
Cancel Common Factors: Cancel out common factors from the numerator and denominator.The (x+8) terms cancel out, and the (x+3) terms cancel out.The expression simplifies to (x−3)1×4x3.
Multiply Remaining Expressions: Multiply the remaining expressions.Multiplying (x−3)1 by 4x3 gives 4(x−3)x3.
Check for Further Simplification: Check for any further simplification. There are no common factors to cancel out, and the expression is already in its simplest form.
