• Polynomials in fraction form

• Simple integers

In the context of rational expressions, what does factoring help achieve?

• Solution of equations

• Conversion to decimal form

• Preparation for integration

• Simplification by canceling terms

When dividing a polynomial by a monomial, what is the first step?

• Multiply the terms

• Subtract the exponents

• Divide each term by the monomial

• Add the exponents

What happens to common terms in the numerator and denominator?

• They are multiplied

• They are subtracted

• They cancel each other out

• They are squared

What is the result of simplifying the expression with common terms x - 8 and x + 8?

• Cannot be simplified further

• x - 8
