Bring the 35 to the Left hand side, then use the quadratic equation (if you cant find the factors in an easier way).
You start it, I can fill in your blanks : ) 👍

3m^2  8m  35 = 0,
A*C = 3*(35) = 105 = 7 * (15),
Choose the set of factors whose sum = 8.
3m^2 + (7m  15m)  35 = 0,
(3m^2 + 7m) + (15m  35) = 0,
m(3m + 7)  5(3m + 7) = 0,
(3m + 7)(m  5) = 0,
3m + 7 = 0, m = 7/3.
m5 = 0, m = 5. 👍
