2x(x-24)=50
⇒2x²-48x=50
2x²-48x-50=0 (now seperate 48x into two parts)
2x²-50x+2x-50=0 (take common from both the equation)
2x(x-25)+2(x-25)=0( Now x-25 is common in both )
(2x+2)(x-25)=0( to make the equation equal from both sides we have to take the value of x such a number that the whole equation becomes zero)
So x=-2 or x= 25
so that's it if you like the answer please mark it as brainlist
Hope it helped you
