Q. Simplify the following expression completely.x2−2x−48x2−6x−16Answer:
Factorization: Factor the numerator and the denominator.The numerator x2−6x−16 can be factored into (x−8)(x+2).The denominator x2−2x−48 can be factored into (x−8)(x+6).
Cancel Common Factors: Cancel out the common factors.The common factor in the numerator and the denominator is (x−8).So, we cancel (x−8) from both the numerator and the denominator.(x−8)(x+2)/(x−8)(x+6) becomes (x+2)/(x+6).
Write Simplified Expression: Write the simplified expression.After canceling the common factor, the simplified expression is (x+2)/(x+6).
