Question

(13m^4+2) + (m^4 n^2 - 2m^4)                      
- (-13m^2 n^3 + 5m^4) simplify?

anonymous · Answer

Distribute the signs (or +1 and -1) and then collect like terms?  That's how I'd approach the problem.

anonymous · Answer

can you show me @KinzaN

anonymous · Answer

The first bracket can be opened, which would just make it
13m^4+2

the second bracket as well,
m^4n^2-2m^4

and finally the third,
13m^2n^3-5m^4

Then you just collect the like terms.

ok let me see

fanduekisses · Answer

i got it it's 7m^4 + n^3 +14m^2 +2

anonymous · Answer

can you work it out please

fanduekisses · Answer

sure :)

fanduekisses · Answer

ok so first, you must know that whenever there is a (-) sign before parenthesis like for ex: -(-13m^2+5m) you change all the signs after it so it becomes +(+13m^2-5m)

fanduekisses · Answer

so the - (-13m^2 n^3 + 5m^4), became + (+13m^2 n^3 - 5m^4)

fanduekisses · Answer

now you add all of the like terms together, like 13m^4 , m^4, -2m^4, and -5m^4 = 7m^4

fanduekisses · Answer

then add n^2 and 13m^2= 14m^2
