Answer:
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
→2a + b gets cancelled.
→ -2ab = (2x)(2a+b+2x)
→ -2ab = 4ax + 2bx + 4x²
→4x2 + 2bx + 4ax + 2ab = 0
→2x(2x + b) + 2a(2x + b) = 0
→ (2x +2a)(2x + b) = 0
→2x + 2a = 0
→x = - a 2x + b = 0
x = - b / 2
So, x = -a , -b/2
