Multiply harder to factor rational expressions

What is the first step in factoring a perfect square trinomial?

• Multiply all terms together

• Divide the expression by a common factor

• Identify and group terms that can be factored

• Combine all terms into a single fraction

When rewriting expressions as a single fraction, what must be true about the terms?

• They must be even numbers

• They must be perfect squares

• They must be separated by multiplication

• They must be separated by addition

What happens when you cancel out common factors in a fraction?

• The expression is simplified

• The expression becomes more complex

• The expression becomes a perfect square

• The expression remains unchanged

What is a restriction in the domain of an expression?

• A value that makes the expression undefined

• A value that makes the expression negative

• A value that makes the expression zero

• A value that makes the expression a perfect square

Why are imaginary numbers not considered when determining domain restrictions?

• They are always zero

• They are always positive

• They do not affect the expression

• They are not real numbers
