Grouping Four Term Polynomials

When do you use grouping?

• When the ends are perfect squares

• When it is a binomial

• When it is a trinomial

• When the polynomial has four terms.

What are the factors of x² - 4x - 3x + 12?

• (x + 3)(x + 4)

• (x - 3)(x - 4)

• (x + 3)(x - 4)

• (x - 3)(x + 4)

What is the purpose of factoring by grouping?

• To use the Distributive Property to factor a polynomial with four terms.

• To combine like terms in a polynomial.

• To expand a polynomial into a sum of terms.

• To simplify a polynomial by dividing by a common factor.

Factor by grouping:
4p³+8p²+3p+6

• (2p²+3)(p+2)

• (2p²+6)(p+4)

• (4p²+3)(p+2)

• (4p²+8p)(3p+6)

When using factor by grouping, how many terms must we have?

• Four or more

• Two

• Three

• Doesn't matter

Find the sum.
(3y² + y³ - 5) + (4y² -4y + 2y³ + 8)

• 3y³ + 7y² - 4y + 3

• 4y² + 3y³ - y + 3

• -y⁴ + 2y³ -y - 4

• 4y³ + 3y² -3y + 1
