Q. Simplify the expression completely if possible.x2−9x2−11x+24Answer:
Factor Numerator and Denominator: Factor the numerator and the denominator if possible.The numerator x2−11x+24 can be factored into (x−8)(x−3) because 8 and 3 are the numbers that multiply to 24 and add up to −11.The denominator x2−9 is a difference of squares and can be factored into (x+3)(x−3).
Write Factored Form: Write the factored form of the expression.The expression becomes (x+3)(x−3)(x−8)(x−3).
Cancel Common Factors: Cancel out the common factors.The (x−3) term is present in both the numerator and the denominator, so they cancel each other out.The expression simplifies to x+3x−8.
Check Further Simplifications: Check for any further simplifications. There are no common factors left, and neither the numerator nor the denominator can be factored further. Therefore, the expression is fully simplified.
