How I do this : Simplify 4B3-1b+2b+2b3+2 ? Please i need some help with math
Firstly, do you mean
$$4B^3-1b+2b+2b^3+2b \mbox{ ? }$$
If so the most common way to write it (for question askers) is 4B^3-1b+2b+2b^3+2b
The hat ^ is used for 'to the power of'. That is a handy thing for you to know.
Now back to the question, as I have interpreted it.
It is very unusual to use a little b and a Capital B in the same question but I am going to assume that they are different pronumerals that you cannot add or subtract together.
You can only add and subtract like terms - these must have the same letters (pronumerals) and the letters must be raised to the same power.
The only terms you can add are -1b+2b+2b which equals 3b
so the answer is $$4B^3+2b^3+3b$$
