(13m^4+2) + (m^4 n^2 - 2m^4) - (-13m^2 n^3 + 5m^4) simplify?
Distribute the signs (or +1 and -1) and then collect like terms? That's how I'd approach the problem.
can you show me @KinzaN
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.
@Fanduekisses ??
ok let me see
i got it it's 7m^4 + n^3 +14m^2 +2
can you work it out please
sure :)
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)
so the - (-13m^2 n^3 + 5m^4), became + (+13m^2 n^3 - 5m^4)
now you add all of the like terms together, like 13m^4 , m^4, -2m^4, and -5m^4 = 7m^4
then add n^2 and 13m^2= 14m^2
