Add two rational expressions and then label the constraints of the solution

The video tutorial explains how to determine the least common denominator (LCD) and multiply expressions. It guides through simplifying expressions by combining like terms and identifying constraints on variable values. The process involves multiplying expressions, simplifying them, and understanding the constraints where certain values are not permissible for variables.

What is the first step in determining the Least Common Denominator (LCD)?

• Subtract the terms

• Divide the terms by each other

• Multiply the terms to find the product

• Add the terms together

When simplifying the expression, what do you do with like terms?

• Combine them

• Multiply them

• Divide them

• Ignore them

What is the result of combining the variables 2X and X?

• 3X

• 2X

• X

• 4X

What are the constraints on the variable X in the expression?

• X cannot equal 5 and -3

• X cannot equal -5 and -3

• X cannot equal 0

• X cannot equal -5 and 3

What is the next step after identifying the constraints on X?

• Simplify the expression

• Multiply the expression further

• Divide the expression

• Add the terms
