The word "solve" suggests an equation which , in turn , requires an = sign:-
m ² + 2 m - 15 = 0
( m + 5 ) ( m - 3 ) = 0
m = - 5 , m = 3

You can factor the expression into
(m+5)(m-3)
but you cannot "solve" it without it equaling anything. If it was supposed to equal zero, then you take the above factorization and set each part equal to zero.
m+5=0 m-3=0
m=-5 or m=3

It depends on what the equation is set equal to, but for my explanation it will be zero.
m^2+2m-15=0
First factor the equation.
(m+5)(m-3)=0
Set term equal to zero and solve for m.
m+5=0
m= -5
m-3=0
m= 3
The answer can be either 3 or -5 (only if the function is equal 0)

m2 + 2m - 15
=(m+5)(m-3)

(m+5)(m-3) factor the 15

2m + m2 - 15 = 4m - 15
If ur trying to solve for m, then i guess M would have to equal 15/4
Oh.. is that a squared? o.o u should have used ^ for ur exponent.. =P Daniels got it then, factor it

you can't... it's not an equation, you need an equals (=) somewhere
You can simplify it by combining like terms (m), in which case you would have 4m - 15

if u want to factor it..it is
(m+5)(m-3)

solve what? the above expression equated to zero or what? your question is incomplete!
