(Section 0.8: Factoring Rational and Algebraic Expressions) 0.8.2 Example 1 (Factoring with Negative Exponents)Factor x±7+x±4±2x±1over the integers. § SolutionObserve that ±7is the leastexponent on x. Our GCFis x±7, so we will factor it out and subtract ±7from each of the exponents. x±7+x±4±2x±1=x±71+x±4±±7()±2x±17=x±71+x±4+7±2x±1+7=x±71+x3±2x6TIP 2:Observe that this last trinomial has no negative exponentson x. This is a sign that we have factored out the GCF correctly. WARNING 1: We usually try to avoidnegative exponentsin final answers, so we will rewrite the
