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

3%282m-5%29=8m%5E2%2B4

You can try to solve this is see how well it goes.
6m-15=8m%5E2%2B4
8m%5E2-6m%2B15%2B4=0
8m%5E2-6m%2B19=0

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

m=%286%2B-+sqrt%2836-4%2A8%2A%2819%29%29%29%2F%282%2A8%29, which contains an imaginary component
