Multiply entire equation by least common denominator example: You must show work and your answers must be correct to get credit. Solve each equation and check for extraneous solutions. Web solving rational equations solve the following equations using the lcd to clear fractions first. An equation containing at least one fraction whose numerator and denominator are polynomials is known as rational equations.
Solve each equation and check for extraneous solutions. Remember from lesson 7 that rational expressions are simply fractions containing polynomials, so each equation we work with today will contain fractions. You must show work and your answers must be correct to get credit. Obtain critical points by equating the numerator and denominator to zero.
For example, the equation 2x + 3 = 5 is not a rational equation because there are no fractions present.
