Question

(x+y)^3 + (y-2x) ^3+(x-2y) ^3​

Answer 1

Answer:

the correct answer is= x^ 3+ y ^ 3+ y^ 3- 6x^ 3+ x^ 3 - 6y ^ 3

Answer 2

Step-by-step explanation:

here is your answer

3x−2y=5............ (1)

3y−2x=3

−2x+3y=3

Multiply (1) by 2 & eq (2) by 3

6x−4y=10..........(3)

−6x+9y=19..........(4)

_______________

Adding eqn (3) and (4), we get

6x−4y=10

−6x+9y=19
