Section 5.3

 Adding or Subtracting requires common denominators like numerical fractions  You will need to figure out the LCD by finding the LCM of the denominators  How to find LCM: ◦ Factor each polynomial ◦ Write any repeated factors as powers ◦ LCM is each different factor to its highest exponent.

 To add or subtract with unlike denominators ◦ Find the LCD ◦ Rewrite each fraction as an equivalent fraction over the LCD ◦ Check your answers ◦ Some answers may be extraneous solutions

 Day 1: page #17-27, 33-41  Day 2: page #28-30, 43-45, 49-51,  Accelerated add: 53-57
