When adding and subtracting fractions it is important for us only to combine terms when they have the same denominator. This holds true for rational expressions. Therefore are first step will be to determine the LCM of our denominators which we often call the LCD. We then multiply both the numerator and denominator by values or terms that will provide the LCD for both terms. We need to make sure we multiply both numerator an denominator by our value and terms to keep equivalent fractions so we are not changing the problem. Once we have two or more terms with common denominators we can then combine the numerators over the LCD. (2i/(2+i))+(5/(2‐i))\n
