Question

(i) (a+b): (a²-b2) =(ac+bd): (ac-bd)​

Answer 1

Answer:

(ac-bd)​ = (ac+bd) (a-b)

Step-by-step explanation:

(a+b): (a²-b²) =(ac+bd): (ac-bd)​

If a: b :: c: d

Then a/b = c/d

(a+b/ (a²-b²) =(ac+bd)/ (ac-bd)​

(a + b) (ac-bd)​ = (ac+bd) (a²-b²)

We know that (a²-b²) = (a-b) (a +b)

(a + b) (ac-bd)​ = (ac+bd) ((a-b) (a +b)

(ac-bd)​ = (ac+bd) (a-b)
