We do this because when the equation is multiplied by the LCD, the common factors in the LCD and in each denominator will equal one and will cancel out. Example 3: Solving a Rational Equation Solve the rational equation: 72x−53x=22372x−53x=223. Solution We have three denominators;...
In the following video, we present an example of solving a rational equation with variables in the denominator.You have seen that there is more than one way to solve rational equations. Because both of these techniques manipulate and rewrite terms, sometimes they can produce solutions that do ...
Solving rationals III An equation that contains at least on rational expression is called a rational equation. You solve a rational equation as you solve any other equation. Example x−32x+3x=5⇒x−32x+2⋅32⋅x=5⇒ x−3+62x=5⇒x+32x=5⇒ ...
I'm only saying that it's simpler.) This is because, as soon as you go from a rational expression (that is, something with no "equals" sign in it) to a rational equation (that is, something with an "equals" sign in the middle), you get a whole different set of tools to work ...

Solving a Rational Equation Let's begin by looking at solving an equation with rational functions in it. I'll give you a simple equation for the sake of keeping the steps clear. The steps are the same, no matter how big the rational functions are. What you need to know to get started...
If there is more than one expression on a side of the equation, you cannot cross multiply. 3x - 5 = 5 x+5 2 x+5 See how there are two expressions on the left side. Solving Rational Equations Multiply by the LCD 3x - 5 = 5 LCD (x+5)(2) ...

The radical equation is an algebraic expression with a variable inside a root, separated by an equals sign. To solve these equations, we must isolate the variable until we find its result. We can extract the variable from the square root throug...
