Question

2m (m – 24) = 50
by factorisation method​

Answer 1

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 2

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
