How do you know if it's a rational equation?

When we have an equation where the variable is in the denominator of a quotient, that’s a rational equation. We can solve it by multiplying both sides by the denominator, but we have to look out for extraneous solutions in the process.

How do you evaluate an algebraic expression?

To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number. To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.

How do you multiply rational algebraic expressions?

The method of multiplying rational expressions is same as the method of multiplying fractions . That is, just multiply the numerators to get the numerator of the product and multiply the denominators to get the denominator of the product. For all rational expressions ab and cd with b≠0 and d≠0 , ab⋅cd=acbd .
