Simplify 6m2n3 – 3m3n2 + 8m2n3 + 12m3n2
NISA [10]
Hello! Hope I can assist you.

Let us simplify some terms first!

6m\cdot \:2n\cdot \:3 \ \textgreater \  36mn
3m\cdot \:3n\cdot \:2 \ \textgreater \  2\cdot \:3^2mn
8m\cdot \:2n\cdot \:3 \ \textgreater \  48mn
12m\cdot \:3n\cdot \:2 \ \textgreater \  72mn

36mn-2\cdot \:3^2mn+48mn+72mn

From here, group like terms
36mn-2\cdot \:3^2mn+48mn+72mn

\mathrm{Add\:similar\:elements:}\:36mn+48mn+72mn=156mn
156mn-2\cdot \:3^2mn

2\cdot \:3^2mn \ \textgreater \  2\cdot \:9mn \ \textgreater \  18mn

156mn-18mn

\mathrm{Add\:similar\:elements:}\:156mn-18mn=138mn

Hope this helps!
