Multiplying Binomials (Alg1H)

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

• 2x³ -4x +3

• 2x + 5x -3

• 2x² -5x -3

• 2x -6x + 2

Find the product:
(3x + 2)(2x + 4)

• 6x² + 16x + 8
• 5x² +11x + 6
• 5x² + 16x + 6
• 6x² + 11x + 8

Simplify:
(x - 9)(x - 7)

• x² - 2x - 63
• x² - 16x - 63
• x² - 2x + 63
• x² - 16x + 63

Find the product:
(x + 5)(x - 4)

• x² + 9x + 20
• x² + 9x - 20
• x² + 1x - 20
• x² - 1x - 20

When using the box method you add the binomial on top with the binomial on the left side.

• True

• False

What term should go in the blue box?

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

• They have the same number

• They have the same variable

• They have the same variable/exponent combination

• They have the same sign

• B

• C

• D

What expression goes in the missing box?
