Question

$8x3 + 12x {}^{2} y + 6xy {}^{2} + y 3 \\ - x3 - 3x {}^{2}y - 3xy {}^{2} - y3$
​

Answer 1

Answer:

         7x^3+9x^2y+3xy^2

Step-by-step explanation:

                    $8x^3 +12x^2y +6x^2y+y^3\\-x^3 - 3x^2y - 3xy^2 -y^3\\-----------$  

                    = $7x^3+9x^2y+3xy^2+0$

                    =$7x^3+9x^2y+3xy^2$
