Multiplying Monomial by Binomial

Multiply: 5(3x+2)

• 3x+10

• 15x+10

• 15x-10

• 3x-10

3(x - 5)

• 3x - 5

• x - 15

• 3x - 15

• x + 3 + 15

Answer explanation

Th distributive property. Multiply what's outside the parenthesis by every term inside the parenthesis.

2(a + 3) = 2 x a + 2 x 3

= 2a + 6

3r³(2r² + 5r)

• 6r⁵ + 15r⁴

• 5r³ + 8r³

• 6r⁵ + 15r³

• 5r⁶ + 15r

Answer explanation

Multiply teh coefficients, add the exponents. Multiply what' outside the parenthesis by everything insode the parenthesis.

(2x + 3)(3x + 4)

• 6x² + 17x + 7

• 6x² + 17x + 12

• 6x² + 8x + 12

• 6x² + 9x + 12

(4x + 3)(x + 2)

• x² + 11x + 6

• 4x² + 8x + 6

• 4x² + 3x + 6

• 4x² + 11x + 6

(3x + 1)(2x + 5)

• 6x² + 17 + 5

• 6x + 17x + 5

• 6x² + 17x + 5

• 6x² + 17 + 5x

(2x + 3)(2x + 5)

• 4x² + 16x + 15

• 4x² + 16 + 15

• 4x² + 16x + 15x

• 4x + 16x + 15

(-2x² + 4x + 4)(3x - 5)?

•  -6x³ + 12x² + 15x – 5

•  -6x³ + 22x² + 32x – 20

• . -6x³ + 2x² – 8x – 5

•  -6x3³ + 22x² - 8x – 20

Multiply the following

6h(5h² - 2hz - 4z²)

• 30h³ - 12h²z - 24hz

• 11h³ - 12h²z - 24hz²

• 30h - 12hz - 24 hz²

• 30h³ - 12h²z - 24hz²

Simplify:
2x ( -2x -3)

• -4x - 3

• x² - 3

• -4x² - 6x

• -4x - 6
