Answer 1

A). (3x)(9x²y)

3x × (9x²y)

3x × 9x²y

27x¹ × x²y

27x ^ 1+2

= 27x³y

B). (- 5a³)(a⁸ - 3a⁶b² + a⁴b⁴ - 3a²b⁶)

-5a³ × (a⁸ - 3a⁶ b² + a⁴b⁴ - 3a²b⁶)

= - 5a¹¹ + 15a⁹b² - 5a⁷b⁴ + 15a⁵b⁶

C). (x + 3)(x - 1)

x × x - x + 3x - 3

x² - x + 3x - 3

= x² + 2x - 3

D). (a² + ab + b²)(a - b)

= a³ - b³
