3 h 2 − 4 g 4 + 7 + 7 f 2 + 9 g 4 − 4 h 2 + f 2 − 2
You might be missing parts of you're question because it was written in LaTex. Can you please check if there are any missing parts to your question, i.e. exponents.
Thanks!
3h2 - 4g4 + 7 + 7f2 + 9g4 - 4h2 + f2 - 2
Rewriting, putting like terms together:
(3h2 - 4h2) + (-4g4 + 9g4) + (7 - 2) + (7f2 + f2)
= - h2 + 5g4 + 5 + 8t2
+934
