Combining Like Terms Challenge

What is the first step in combining like terms?

• Rewriting the expression

• Combining the coefficients

• Identifying the like terms

• Combining the constants

In the first example, why can't the terms x^2y and xy^2 be combined?

• They are both constants

• They have different coefficients

• They have different variables

• They have different exponents

What is the result of combining 8x^2y and -5x^2y?

• 3xy

• 3x^2

• 3x^2y

• 3x

In the second example, what is the coefficient of the term -x?

• 0

• 1

• -1

• 2

What is the simplified form of 13 - 15?

• -2

• 2

• 28

• -28

How do you combine -1x and 12x?

• 11

• 11x

• 12x

• -1x

In the third example, why can't 5x^2 and -3x be combined?

• They have different coefficients

• They have different variables

• They have different exponents

• One is a constant

What is the simplified form of 5x^2 - 3x + 11?

• 5x^2 - 3x

• 5x^2 + 11

• 5x^2 - 3x + 11

• 11 - 3x

What is the definition of like terms?

• Same variables with different exponents

• Different variables with same exponents

• Different variables with different exponents

• Same variables with same exponents

Why is it important to identify like terms before combining them?

• To avoid combining terms incorrectly

• To rewrite the expression

• To ensure the coefficients are the same

• To simplify the expression
