Question

(1/8x^4+2/7x^3+7/8x^2+7)+(-5/8x^4+1/8x^2-7)

Answer 1

\[-1/(2x^4)+2/(7x^3)+1/x^2\]

Answer 2

ok im lost on this

Answer 3

Just to confirm the equation is:
\[(1/8x^4+2/7x^3+7/8x^2+7)+(-5/8x^4+1/8x^2-7)\]
???

Answer 4

yea but i posted a different question after that. you are more than welcome to do that one if you like. its the 1/16x^4 one

Answer 5

I'm guessing it's this
\[(\frac{1}{8}x^{4} + \frac{2}{7}x^{3}+\frac{7}{8}x^{2}+7)+(-\frac{5}{8}x^{4}+\frac{1}{8}x^{2}-7)\]
