Sum of 2a³ -b³ and a³+b²-2b³ is 3 a³ - 3b³ +b².
Step-by-step explanation:
Sum of 2a³ -b³ and a³+b²-2b³
Write in addition format
(2a³ -b³) + (a³+b²-2b³)
Remove bracket
= 2a³ -b³ + a³+b²-2b³
Rearrange similar terms and solve
= 2a³+ a³ -b³ -2b³ +b²
= (2+ 1) a³ + (-1 -2)b³ +b²
= 3 a³ - 3b³ +b²
So, the sum of 2a³ -b³ and a³+b²-2b³ is 3 a³ - 3b³ +b².
