Part 4 of Solving Rational Equations; more examples.
- What is a rational equation?
- How do you solve equations with fractions in them?
- How do you solve equations when x is in the numerators and denominators of the fractions?
- How do you check your solution to a rational equation?
- How do you solve 2/(x - 2) = 8/x - 1?
- How do you know what x cannot equal when solving a rational equation?
- How do you solve 2x = 8(x - 2) - x(x - 2)?
- How do you solve (x + 6)/(x^2 - 4) - 2/(x - 2) = x/(x + 2)?
- How do you solve x + 6 - 2x - 4 = x^2 - 2x?
2 more example problems with fractions are shown in this video. The variable is in the denominator, so the denominators are eliminated in the first problem by multiplying by the least common denominator and then solving the resultant quadratic equation. In the second problem, you will see how to get common denominators and then solve.
