Question

X/a+X/b =a²-b²/ab explain​

Answer 1

Answer:

         X = a - b

Step-by-step explanation:

X / a + X / b = a² - b² / ab

bX + aX / ab = a² - b² / ab

bX + aX  = a² - b²

X (b + a)  = a² - b²                                               { a² - b² = (a+b) (a-b) }

X (b + a)  = (a + b) (a - b)

X  = (a + b) (a - b) / (b + a)

X = a - b
