How to subtract rational expressions that already have a common denominator, and how to simplify if it is possible to cancel.
- How do you subtract and simplify rational expressions that have a common denominator?
- How do you subtract rational expressions if a numerator has more than one term?
- How do you subtract and simplify 4x/(x - 1) - 4/(x - 1)?
- How can you subtract and simplify (5x - 8)/(2x + 3) - (2x + 6)/(2x + 3)?
- Why does -(2x + 6) equal -2x - 6?
- How do you subtract, factor, and simplify (x^2 + 9x)/(x + 7) - (4x + 14)/(x + 7)?
- What does (3x + 4)/(2x^2 + 5x - 3) - (5x + 3)/(2x^2 + 5x - 3) equal?
- How do you know if you can simplify (-2x + 1)/((2x - 1)(x + 3))?
This video is very similar to the last video on adding rational expressions with common denominators. This time, however, we are subtracting. This is similar, but you must be careful to distribute the - sign to all terms being subtracted. This has some great example problems explained very well.
