## What is rational equation and example?

Equations that contain rational expressions are called rational equations. For example, 2x+14=7x 2 x + 1 4 = 7 x is a rational equation. Rational equations can be useful for representing real-life situations and for finding answers to real problems.

What is the formula for rational equation?

A rational equation is an equation containing at least one fraction whose numerator and denominator are polynomials, \frac{P(x)}{Q(x)}. Q(x)P(x). These fractions may be on one or both sides of the equation.

### How do you solve a rational inequality step by step?

To solve a rational inequality, we follow these steps:

1. Put the inequality in general form.
2. Set the numerator and denominator equal to zero and solve.
3. Plot the critical values on a number line, breaking the number line into intervals.
4. Take a test number from each interval and plug it into the original inequality.

– √ (2x+9) – 5 = 0 First, move everything that isn’t under the radical sign to the other side of the equation: – √ (2x+9) = 5 – Then, square both sides to remove the radical: – (√ (2x+9)) 2 = 5 2 = – 2x + 9 = 25 Now, solve the equation as you normally would by combining the constants and isolating the variable: – 2x = 25 – 9 = – 2x = 16 – x = 8
