How to subtract two binomials

The video tutorial explains how to subtract polynomials by ensuring they have the same base and degree. It introduces a method to convert subtraction problems into addition problems by distributing the negative sign. The tutorial emphasizes aligning variables correctly to combine like terms effectively.

What is necessary for two polynomials to be subtracted from each other?

• They must be in standard form.

• They must have the same base and degree.

• They must have the same coefficients.

• They must have different variables.

What is the first step in converting a subtraction problem into an addition problem?

• Factor the expression.

• Align the variables.

• Distribute the negative sign.

• Combine like terms.

What happens to the expression 5A + 9B - 2A - 4B when the negative sign is distributed?

• It becomes 5A + 9B + 2A - 4B.

• It becomes 5A + 9B - 2A - 4B.

• It becomes 5A - 9B - 2A + 4B.

• It becomes 5A + 9B + 2A + 4B.

Why is it important to align variables when solving polynomial expressions?

• To ensure the expression is in standard form.

• To simplify the coefficients.

• To correctly combine like terms.

• To make it easier to factor the expression.

Which of the following expressions can be combined?

• 3A and 4B

• 9B and 5A

• 5A and -2A

• 2A and 3C
