Combining like terms of an expression ex3

The video tutorial explains how to combine like terms in algebra by focusing on variable factors. It emphasizes that terms can only be combined if they have identical variable factors. The tutorial provides examples to illustrate this concept and concludes with a demonstration of simplifying an expression. The process is kept concise, aiming to complete the explanation within two minutes.

What is necessary for terms to be combined when dealing with like terms?

• They must have the same coefficients.

• They must have the same variable factors.

• They must be in the same equation.

• They must be on the same side of the equation.

Which of the following pairs of terms can be combined?

• X^3Y and XY^3

• X^2Y and X^3Y^2

• X^2Y^2 and X^2Y^2

• XY^2 and X^2Y

Why can't the terms X^2Y and X^2Y^2 be combined?

• They have different coefficients.

• They have different variable factors.

• They are on different sides of the equation.

• They are in different equations.

In the hypothetical scenario, what operation is performed on the terms?

• Subtraction

• Addition

• Division

• Multiplication

What is the result of combining the terms -8 and -4 in the hypothetical scenario?

• 4

• -12

• 12

• -4
