Answer:
m=25 OR m=-1
Step-by-step explanation:
(2m) square-48m=50
m2-24m-25=0
m2+m-25m-25=0
m(m+1)-25(m+1)=0
m-25)(m+1)=0
(m-25)=0 OR (m+1)=0
m=25 OR m=-1

Answer:
this is the answer as follows.......
Step-by-step explanation:
2m (m – 24) = 50
2m^2 - 48m = 50
2m^2 - 48m - 50 =0
2(m^2 - 24m -25) =0
m^2 - 24m -25=0
m^2 - 25m + m-25 =0
m(m-25)+1(m-25)=0
(m+1)(m-25)=0
from this we derive two cases whether first
m+1 =0
m=-1
or
m-25=0
m=25
thus m is either -1 or 25
