Factoring

What is the first step in factoring a polynomial with three terms?

• Look for a greatest common factor

• Factor into two binomials

• Identify the trinomial

• Divide by the leading coefficient

When factoring 8x^3 - 40x^2 - 48x, what is the greatest common factor?

• 8x

• 4x

• 16x

• 2x

After taking out the greatest common factor, what type of polynomial is inside the parenthesis for 8x^3 - 40x^2 - 48x?

• Monomial

• Quadratic

• Trinomial

• Binomial

What mistake do people often make after factoring out the greatest common factor?

• They divide the remaining terms

• They add instead of subtract

• They stop, thinking they are done

• They multiply the factors
