Apply the Distributive Property to multiply 3a ^ 3 * b ^ 2 * (6ab + 7a ^ 2 * b)

18a ^ 2 * b ^ 2 + 21a ^ 6 * b ^ 2

9a ^ 4 * b ^ 3 + 10a ^ 5 * b ^ 3

18a ^ 4 * b ^ 3 + 21a ^ 5 * b ^ 3

9a ^ 3 * b ^ 2 + 10a ^ 6 * b ^ 2
The correct answer is 18a^4 * b^3 + 21a^5 * b^3.
Multiply (x + 3)(x - 2)

x ^ 2 - 5x + 6

x ^ 2 + 5x + 6

x ^ 2 + x - 6

x ^ 2 - 6
The correct answer is x^2 + x - 6.
Apply the Distributive Property to multiply (x - 5)(x - 1)

x ^ 2 + 6x + 5

x ^ 2 + 5

x ^ 2 - 5x + 5

x ^ 2 - 6x + 5
The correct answer is x^2 - 6x + 5.
