Question

2m(m-24)=50
$2m(m - 24) = 50$
​

Answer 1

Answer:

It is given that ,

2m( m - 24 ) = 50

m( m - 24 ) = 50/2

m² - 24m = 25

m² - 24m - 25 = 0

Splitting the middle term, we get

m² - 25m + 1m - 25 = 0

m( m - 25 ) + 1( m - 25 ) = 0

( m - 25 )( m + 1 ) = 0

Therefore ,

m -25 = 0 or m + 1 = 0

m = 25 or m = -1

I hope this helps you.

Answer 2

Answer:

Step-by-step explanation:

distrubutive property can be used in this question

2m(m-24)=50

2m^2-48m=50 or m(m-24)=25 but this one is tough to solve

2m²-48m-50=0

2(m²-24m-25)=0  distrubutive as 2 is common

m²-24m-25=0

m²-(25-1)m-25=0

m²-25m+m-25=0

m(m-25)+1(m-25)=0

(m+1)(m-25)=0

m= -1 or m=25
