Question

−9x^2y, 4x^2y, −3x^2y​

Answer 1

Step-by-step explanation:

STEP 1

:

Equation at the end of step 1

((((9•(x2))•y)-4x)+((3•(y3))•x))-2y2

STEP 2

:

Equation at the end of step 2

:

((((9•(x2))•y)-4x)+(3y3•x))-2y2

STEP 3

:

Equation at the end of step 3

:

(((32x2 • y) - 4x) + 3xy3) - 2y2

STEP 4

:

Checking for a perfect cube

4.1 9x2y+3xy3-4x-2y2 is not a perfect cube

Final result :

9x2y + 3xy3 - 4x - 2y2

Answer 2

Answer:

xy + 4x - 2y2 + 2y

Step-by-step explanation:

STEP

1

:

Equation at the end of step 1

((12x-2y)-(y•(2y-x)))-(2y+2•(4x-3y))

STEP

2

:

Equation at the end of step 2

((12x - 2y) - y • (2y - x)) - (8x - 4y)

STEP

3

:

Final result :

xy + 4x - 2y2 + 2y
