Question

please answer this question.​

Answer 1

Answer:

a) (3x-y)(9x^2 + y^2 + 3y)

Answer 2

Answer:

Rewrite it in the form a3 −b3, where

a=3x and b=y

2 Use Difference of Cubes: a3 −b 3

=(a−b)(a2 +ab+b 2 )

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

3 Use Multiplication Distributive Property: (xy)a =xa ya

.

(3x-y)(32x2 +3xy+y 2)

4 Simplify 3 to 9.

(3x−y)(9x2 +3xy+y 2)
