1/(2a + b +2x) = 1/2a + 1/b + 1/2x
1/(2a + b +2x) -1/2x =1/2a + 1/b
{ 2x - 2a - b -2x} /2x(2a + b +2x) =(2a + b)/2ab
-(2a + b)/2x(2a + b +2x) = (2a + b)/2ab
-1/x(2a + b +2x ) = 1/ab
-x(2a + b +2x ) = ab
2x^2 +(2a + b)x + ab =0
2x^2 +2ax +bx + ab =0
2x( x + a) + b (x + a ) =0
(2x + b) ( x + a ) =0
x = -b/2 , -a
1/(2a + b +2x) -1/2x =1/2a + 1/b
{ 2x - 2a - b -2x} /2x(2a + b +2x) =(2a + b)/2ab
-(2a + b)/2x(2a + b +2x) = (2a + b)/2ab
-1/x(2a + b +2x ) = 1/ab
-x(2a + b +2x ) = ab
2x^2 +(2a + b)x + ab =0
2x^2 +2ax +bx + ab =0
2x( x + a) + b (x + a ) =0
(2x + b) ( x + a ) =0
x = -b/2 , -a
abhi178:
now you take common minus
yes you are right
now , according to you -1(2a +b)
now, -1(2a +b)/2x (2a + b+2x) =(2a +b)/2ab
now you see (2a + b) is in both sides
so , cut
remains -1/x(2a + b +2x) = 1/ab
now proceed
send me ur whatsapp no.
