Combining Like Terms and Constants

The video tutorial explains how to combine like terms with negative coefficients. It begins by identifying terms that can be combined, focusing on those without variables. The tutorial demonstrates using a calculator to handle double negatives and shows examples of combining terms with variables and constants. The video concludes with advanced examples involving complex terms and double negatives, emphasizing careful calculation.

What is the first step in combining like terms with negative coefficients?

• Subtract all terms

• Add all terms together

• Multiply all terms

• Identify terms that can be combined

Why can't the term -2K be combined with the other terms in the first example?

• It is a positive term

• It is already simplified

• It is a constant

• It has a different variable

What is the result of combining -5 and 1 in the first example?

• 6

• 4

• -6

• -4

In the second example, which terms are identified as alike?

• Terms with the same variable

• Terms with different variables

• All terms

• Only constant terms

• 3N

• 9N

• -9N

• -3N

What is the result of combining -7 and 1 in the second example?

• 6

• -6

• -8

• 8

What is the result of combining -7 and 1 in the second example?

• -6

• -8

• 6

• 8

What is the result of combining -3N and -6N?

• -3N

In the final example, what is the result of combining -4Q and -(-8Q)?

• -4Q

• 12Q

• 4Q

• -12Q

What is the significance of double negatives in the final example?

• They cancel each other out

• They double the value

• They make the term positive

• They have no effect
