Q. Simplify the expression completely if possible.x4−x3x2−11x+18Answer:
Factor Numerator and Denominator: First, factor the numerator and the denominator if possible. The numerator is a quadratic expression that can be factored into two binomials. The denominator is a polynomial that can be factored by taking out the common factor x3.
Factor Numerator: Factor the numerator (x2−11x+18). We look for two numbers that multiply to 18 and add up to −11. These numbers are −9 and −2. So, (x2−11x+18)=(x−9)(x−2).
Factor Denominator: Factor the denominator x4−x3. We can factor out an x3, leaving us with x3(x−1). So, (x4−x3)=x3(x−1).
Simplify Expression: Now we simplify the expression by dividing the numerator by the denominator.We have (x−9)(x−2)/[x3(x−1)].We notice that there are no common factors between the numerator and the denominator, so the expression cannot be simplified further.
Final Answer: The final simplified expression is (x−9)(x−2)/[x3(x−1)]. Since we cannot simplify it further, this is our final answer.
