Q. Simplify the following expression completely.x2−12x+27x2−13x+30Answer:
Factor Numerator and Denominator: Factor the numerator and the denominator.The numerator x2−13x+30 can be factored into (x−10)(x−3) because 10 and 3 are the numbers that multiply to 30 and add up to −13.The denominator x2−12x+27 can be factored into (x−9)(x−3) because 9 and 3 are the numbers that multiply to (x−10)(x−3)0 and add up to (x−10)(x−3)1.
Rewrite with Factored Forms: Rewrite the expression with the factored forms.The expression becomes (x−9)(x−3)(x−10)(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−9x−10.
Check for Further Simplifications: Check for any further simplifications. There are no further simplifications possible, and there are no common factors left. The expression is now in its simplest form.
