Question 823894
Wording is sometimes not as precise as symbolism.  This may be what the description says:


{{{3(2m-5)=8m^2+4}}}


You can try to solve this is see how well it goes.
{{{6m-15=8m^2+4}}}
{{{8m^2-6m+15+4=0}}}
{{{8m^2-6m+19=0}}}


I would not try to factor, but instead use the general solution.


{{{m=(6+- sqrt(36-4*8*(19)))/(2*8)}}}, which contains an imaginary component
