Question

Subtract x ^ 3 - 2x * y ^ 2 + 5x ^ 2 * y - 6 from x ^ 3 + 3x ^ 2 * y + 3x * y ^ 2 - 2 .​

Answer 1

Step-by-step explanation:

The subtraction is carried out as follows,

(y3−3xy2−4x2y)−(x3+2x2y+6xy2−y3)

=y3−3xy2−4x2y−x3−2x2y−6xy2+y3

Rearranging the like terms together,

=(y3+y3)+(−3xy2−6xy2)+(−4x2y−2x2y)−x3

=2y3−9xy2−6x2y−x3
