To solve for m do the following:
1.) Multiply 2m-16 by m to get:
-->2%28m%5E2%29-16m=12
2.) Subtract 12 from both sides to get:
--> 2%28m%5E2%29-16m-12=0
3. Solve for m using your favorie method of solving quadratics.

m(2m-16)=12
2m^2-16m-12=0
2(m^2-8m-6)=0
m+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
m=(8+-sqrt[-8^2-4*1*-6])/281
m=(8+-sqrt[64+24])/2
m=(8+-sqrt88)/2
m=(8+-9.38)/2
m=(8+9.38)/2
m=17.38/2
m=8.69 ans.
m=(8-9.38)/2
m=-1.38/2
m=-.69 ans.
