Help with exponents

[cchope]

Hi everyone! I'm working on my math and I have honestly no clue how to go about this question, the textbook doesn't help much either

Solve for m for the equation:
2m³-1000=-352+5m³

Thank you for any help!!

move all terms to one side & combine ...

[MATH]3m^3+648=0[/MATH]
[MATH]3(m^3+216)=0[/MATH]
divide both sides by 3 ...

[MATH]m^3+6^3=0[/MATH]
do you know the factoring pattern for [MATH]a^3+b^3[/MATH] ?

First step is to simplify and apply "factor of sum of cubes".
