• The ratio and proportion

• The square and cube

• The sum and product

• The difference and quotient

What is the result of alpha plus beta in the given problem?

• Two

• Positive four

• Zero

• Negative four

What is the first step when dealing with fractions in alpha-beta problems?

• Find a common denominator

• Add them directly

• Multiply them

• Subtract them

What operation is often necessary when dealing with cubes in alpha-beta problems?

• Division

• Expansion

• Simplification

• Subtraction

Which identity is useful for simplifying the sum of cubes?

• Product of roots

• Sum of cubes

• Sum of squares

• Difference of squares

What should you do with the identity for the sum of cubes?

• Use it to simplify the numerator

• Apply it to the denominator

• Use it to find the product

Why is squaring not sufficient for separating alpha and beta?

• It results in a negative value

• It combines them into a single term

• It increases the complexity

• It makes the equation unsolvable
