Solving a rational equation by using the LCD

What is the primary goal when adding and subtracting rational expressions?

• To eliminate the fractions

• To find the value of X

• To combine them into one expression

• To solve for the common denominator

What is the purpose of multiplying every term by the LCD in an equation?

• To add fractions

• To find the value of X

• To eliminate fractions

• To combine like terms

After eliminating fractions, what is the next step in solving the equation?

• Add fractions

• Combine like terms

• Check the solution

• Find the LCD

Why is it important to verify the solution of an equation?

• To combine like terms

• To add fractions

• To find the LCD

• To ensure it doesn't make any denominator zero

What should you do if a solution makes a denominator zero?

• Accept the solution

• Ignore the solution

• Write 'no solution'

• Multiply by the LCD again
