$3a ^{3} b ^{2} + 2 {a}^{2} b ^{3} + 6 {a}^{3} b ^{3}$
and
$a ^{3} b ^{2} + 3{a}^{2} b ^{3} - {a}^{3} b ^{3}$
be increased to get
$5a ^{3} b ^{2} + 2 {a}^{2} b ^{3} + 8{a}^{3} b ^{3}$
​

Answer 1

Answer:

a³b²-3a²b³+3a³b³

Step-by-step explanation:

5a³b²+2a²b³+8a³b³-(3a³b²+2a²b³+6a³b³+a³b²+3a²b³-a³b³)

5a³b²+2a²b³+8a³b³-3a³b²-2a²b³-6a³b³-a³b²-3a²b³+a³b³

a³b²-3a²b³+3a³b³
