Q. Simplify the expression completely if possible.x2−8x+74x2−4xAnswer:
Factor Numerator and Denominator: Factor the numerator and the denominator.The numerator 4x2−4x can be factored by taking out the common factor of 4x, resulting in 4x(x−1).The denominator x2−8x+7 can be factored into (x−7)(x−1) because these are the factors of 7 that add up to −8.So, the expression becomes (x−7)(x−1)4x(x−1).
Cancel Common Factors: Cancel out the common factors.The factor (x−1) is present in both the numerator and the denominator, so we can cancel it out.This leaves us with (x−7)4x.
Check Further Simplification: Check for any further simplification. There are no common factors left in the numerator and the denominator, and we cannot simplify the expression any further.
