Select the answer that completes the box with the correct terms. The terms are listed in 1, 2, 3, 4 order as shown in the box.

Write the expanded (general) form of the product (x+3)(x+6).

• x²+18x+9

• x²+9x+18

• x²+18x+18

Simplify

5x (-3x + 5)

• -8x² + 10x

• -15x² + 25x

• 15x² + 25

• -15x + 25

Multiply binomials using box method (2x +1) (x - 3).

• 2x³ -4x +3

• 2x + 5x -3

• 2x² -5x -3

• 2x -6x + 2

What does it mean for two terms to be considered "like terms"

• They have the same number
