**Reiny**, Saturday, May 15, 2010 at 10:11pmfirst one, I think you mean

4m^2 + 20m + 25 = 0

this is a perfect square and factors to

(2m+5)(2m+5) = 0

(2m+5)^2 = 0

m = -5/2

second one, I think you mean

w^3 + 5w^2 - w = 5

factor it by grouping

w^2(w+5) - (w+5) = 0

(w+5)(w^2 - 1) = 0

((w+5)(w+1)(w-1) = 0

w = -5, ± 1
