Let's try!

(2x+1) (x+1)

Multiply the binomials.

Multiply binomials using box method

• 6x^{2 +} 11x -35

• 5x² + 31x - 12

• 6x + 11x - 35

• 5x + 10x +35

(4x+1)(5x−2)

• 20x² + 3x − 2

• 20x² − 11x + 5

• 20x² − 18x + 2

• 20x² − 3x − 2

(2x + 3)(2x - 3)

• 4x² - 9

• 4x² + 9

• 4x²- 12x - 9

• 4x² + 12x - 9

(x + 5)²

• x² + 25

• x² + 10x + 25

• x² + 10 x + 10

• x² + 10

Which rectangle diagram is correct for the product (x+3)(x+6)?

• a

• b

• c

Which rectangle diagram is correct for the product (x-5)(x+2)?

• a

• b

• c

(3x + 2)(x + 1)

• 3x² + 5x + 2

• 3x² + 3x + 3

• 3x² + 5x + 3

• 3x² + 3x + 2

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

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