Question

(x+y)³+(x-y)³+6x(x²-y²)​

Answer 1

Answer:

8x³

Let's simplify step-by-step.

(x+y)3+(x−y)3+6x(x2−y2)

Distribute:

=x3+3x2y+3xy2+y3+x3+−3x2y+3xy2+−y3+(6x)(x2)+(6x)(−y2)

=x3+3x2y+3xy2+y3+x3+−3x2y+3xy2+−y3+6x3+−6xy2

Combine Like Terms:

=x3+3x2y+3xy2+y3+x3+−3x2y+3xy2+−y3+6x3+−6xy2

=(x3+x3+6x3)+(3x2y+−3x2y)+(3xy2+3xy2+−6xy2)+(y³−y³)

=8x3

(note: where ever you find number after x please consider it as power)
