Question

How do you simplify `(4B ^ { 4} - 3B ^ { 3} + 2B ^ { 2} ) + ( B + 2B ^ { 4} + 3B ^ { 3} )`?

Answer 1

`6B^4 +2B^2+B`

Explanation:

`(4B^4 -3B^3 +2B^2)+(B+2B^4+3B^3)`

The first ones you want to add first are the one that have higher exponents: ( `B^4` in this case)

`( 6B^4 -3B^3 +2B^2)+(B+3B^3)`

Then the `B^3`. Since we have nothing to add more because `B^2` and B are different, here's our final answer:

`6B^4 +2B^2+B`
