Solution

## The correct option is D (−2a4−a2b2−3a2b−2ab2)To find out the resulting expression, we have to subtract (3a4−2a2b2+b4+3a2b+2ab2) from (a4−3a2b2+b4) as shown below:(a4−3a2b2+b4)−(3a4−2a2b2+b4+3a2b+2ab2)=a4−3a2b2+b4−3a4+2a2b2−b4−3a2b−2ab2Collecting positive and negative like terms together, we get:=a4−3a4−3a2b2+2a2b2+b4−b4−3a2b−2ab2=−2a4−a2b2−3a2b−2ab2Hence, the resulting expression is (−2a4−a2b2−3a2b−2ab2).
