Using the distributive property from a monomial to a trinomial

The video tutorial explains the distributive property in mathematics, focusing on multiplying a number outside parentheses with each term inside. It covers handling negative numbers and exponents, demonstrating how to add exponents when multiplying terms. The lesson concludes with forming a final expression and addressing common mistakes.

What is the first step when applying the distributive property to an expression?

• Add all the numbers inside the parentheses.

• Multiply the number outside the parentheses with each term inside.

• Subtract the smallest number from the largest.

• Divide the number outside the parentheses by each term inside.

When multiplying terms with exponents, what should you do with the exponents?

• Subtract the exponents.

• Multiply the exponents.

• Add the exponents.

• Divide the exponents.

How do you handle a negative number when using the distributive property?

• Multiply it as a negative number with each term inside the parentheses.

• Treat it as a positive number.

• Add it to the positive numbers.

• Ignore the negative sign.

What is the result of multiplying 3X by X^2?

• 3X^3

• 3X^2

• 3X^4

• 3X

What is the simplified form of the expression 3X^3 + 3X^2 - 12X?

• 3X^3 - 3X^2 + 12X

• 3X^3 + 3X^2 - 12X

• 3X^3 - 3X^2 - 12X

• 3X^3 + 3X^2 + 12X
