Q. Simplify the following expression completely.x2+6x−40x2+5x−50Answer:
Factorize Numerator and Denominator: Factor the numerator and the denominator.The numerator is x2+5x−50, which factors into (x+10)(x−5).The denominator is x2+6x−40, which factors into (x+10)(x−4).
Cancel Common Factors: Cancel out the common factors.The common factor in both the numerator and the denominator is (x+10).So, we cancel (x+10) from both the numerator and the denominator.
Write Simplified Expression: Write down the simplified expression.After canceling out the common factor, the simplified expression is (x−5)/(x−4).
