Question

(x+y)^3-(x-y)^3 can be factories as​

Answer 1

Answer:

xcube - y cube

Step-by-step explanation:

Answer 2

Step-by-step explanation:

(x+y)³ - (x-y)³

= a³ - b³

= (a-b) (a²+ab+b²)

= [(x+y) - (x-y)] [(x+y)² + (x+y) (x-y) + (x-y)²]

= [x+y-x+y] [x²+2xy+y²+ (x²-y²) + (x²-2xy+y²)]

= (y+y) (x²+2xy+y²+x²-y²+x²-2xy+y²)

= 2y (3x²+y²)
