  Since it is not an equation (It does not have an "=" sign.), there is no solution. However, it can be simplified by combining terms. Even so, I am not sure what your terms are. Does (-4k)2+k2 = 2(-4k) + 2k or (-4k)^2 + k^2 where "^2" is the previous term squared? If it is the former, 2(-4k) + 2k = -8k +2k = -6k If it is the latter, (-4k)^2 + k^2 = 16k^2 + k^2 = 17k^2 I hope this helps. Thanks for asking.
