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)
