Tomas learned that the product of the polynomials (a + b)(a2 – ab + b2) was a special pattern that would result in a sum of cubes, a3 + b3. His teacher put four products on the board and asked the class to identify which product would result in a sum of cubes if a = 2x and b = y.

Which term completes the product so that it is the difference of squares?(−5x−3)(−5x+________)

A square with an area of A2 is enlarged to a square with an area of 25A2. How was the side of the smaller square changed?

Which is true about the polynomial –3xy2 + 5x2y?

A square has a perimeter of 12x + 52 units. Which expression represents the side length of the square in units?

The revenue, in dollars, of a company that makes toy cars can be modeled by the polynomial 3x2 + 4x – 60. The cost, in dollars, of producing the toy cars can be modeled by 3x2 – x + 200. The number of toy cars sold is represented by x.

What is the product of (2p + 7)(3p2 + 4p – 3)?

The polynomial 2x3 − 5x2 + 4x − 10 is split into two groups, 2x3 + 4x and −5x2 − 10. The GCFs of each group is then factored out. What is the common binomial factor between the two groups after their GCFs have been factored out?

The diagram represents a difference of squares.

The table represents the multiplication of two binomials.

How could Brent use a rectangle to model the factors of x2 – 7x + 6?

Which model represents the factors of x2 + 9x + 8?

Which algebraic expression is a polynomial with a degree of 4?

The revenue, in dollars, of a company that produces jeans can be modeled by 2x2+17x−175. The cost, in dollars, of producing the jeans can be modeled by 2x2−3x−125. The number of pairs of jeans that have been sold is represented by x. If the profit is the difference between the revenue and the cost, which expression can be used to find profit and what is that profit when 75 pairs of jeans are sold?
