Q. Fully simplify the expression below and write your answer as a single fraction.x5−4x4−60x3x+6⋅x2+12x+275x5−5x4−450x3Answer:
Factor Denominator First Fraction: First, factor the polynomials in the numerator and the denominator where possible.Starting with the denominator of the first fraction: x5−4x4−60x3.Factor out the common term x3: x3(x2−4x−60).Now factor the quadratic: x2−4x−60=(x−10)(x+6).So the denominator becomes: x3(x−10)(x+6).
Factor Numerator Second Fraction: Next, factor the numerator of the second fraction: 5x5−5x4−450x3.Factor out the common term 5x3: 5x3(x2−x−90).Now factor the quadratic: x2−x−90=(x−10)(x+9).So the numerator becomes: 5x3(x−10)(x+9).
Factor Denominator Second Fraction: Now, factor the denominator of the second fraction: x2+12x+27.This is a simple quadratic that factors to: (x+3)(x+9).
Rewrite Expression with Factored Terms: We can now rewrite the entire expression with the factored terms:x3(x−10)(x+6)(x+6)⋅(x+3)(x+9)5x3(x−10)(x+9)
Cancel Common Terms: Next, cancel out the common terms in the numerator and the denominator.The x+6 terms cancel each other, as do the x−10 terms and the x+9 terms.We are left with:x3(x+3)5x3
Cancel Common x^3 Term: Now, cancel out the common x3 term:x+35
Final Simplified Answer: The expression is now fully simplified, and there are no more common terms to cancel.The final answer is:x+35
