Distribute to Compare Expressions

The video tutorial guides students through solving a standardized math test question using the distributive property. The instructor presents a problem, asks students to attempt it, and then demonstrates the solution by distributing terms in an expression. The correct answer is identified, and incorrect options are reviewed to ensure understanding. The session concludes with encouragement to continue learning math.

What is the initial expression given in the problem that needs to be simplified?

• 3 multiplied by (X - 1)

• 3 multiplied by (X + 1)

• 3 multiplied by (X - 2)

• 3 multiplied by (X + 2)

After applying the distributive property, what is the simplified form of the expression 3(X - 1)?

• 3X + 3

• 3X - 3

• 3X + 1

• 3X - 1

Why is the expression X + 5 not equivalent to the original expression?

• It has a different operation.

• It has incorrect coefficients.

• It has a missing variable term.

• It has an extra constant term.

What is the error in choice B, which is X + 2?

• It has an incorrect constant term.

• It has an incorrect variable term.

• It has an extra term.

• It has a missing operation.

Why is choice D, 3X - 1, not equivalent to the original expression?

• The operation is incorrect.

• The expression is missing a term.

• The variable term is incorrect.

• The constant term is incorrect.
