What is the first step in simplifying an algebraic expression?

• Subtract the smallest term from the largest

• Add all terms together

• Identify common terms in the numerator and denominator

• Multiply all terms together

When simplifying y / y, what is the result?

• 1

• y^2

• 0

• y

Which of the following expressions can be factored further?

• y - 3

• 4

• y + 6

• y^2 - y - 6

What is the factored form of y^2 - y - 6?

• (y + 2)(y - 3)

• (y - 2)(y + 3)

• (y + 3)(y - 2)

• (y - 3)(y + 2)

What is the final simplified form of the expression?

• 4 * y - 4 / y + 2

• 4 * y + 4 / y - 2

• 4 * y - 4 / y - 2

• 4 * y + 4 / y + 2
