Q. Perform the following operation and express in simplest form.x2−6xx2−36⋅x2+2x−24x2Answer:
Identify Factors: Identify the factors of the numerator and denominator in each fraction to simplify the expression.(x2−36) can be factored as (x+6)(x−6) because it is a difference of squares.(x2−6x) can be factored as x(x−6) by taking out the common factor x.(x2+2x−24) can be factored as (x+6)(x−4) by finding two numbers that multiply to −24 and add to 2.
Rewrite with Factored Forms: Rewrite the original expression with the factored forms. [x(x−6)(x+6)(x−6)×(x+6)(x−4)x2]
Cancel Common Factors: Cancel out the common factors from the numerator and denominator.The (x−6) terms cancel out, and one (x+6) term cancels out.We are left with:x1×(x−4)x2
Simplify Remaining Expression: Simplify the remaining expression.The x in the denominator and one x from x2 in the numerator cancel out.We are left with:x−4x
Check for Further Simplification: Check for any further simplification. Since x cannot be factored further and there are no common factors left, the expression is now in its simplest form.
