Question

If (x ^ 2 + y ^ 2)/(x ^ 2 - y ^ 2) = 41/9 use componendo and dividendo to find x/y

Answer 1

(a+b) (a-b)=a²-b² -----------------》Third Identity is used here ------------》 [STEP 1]

]so substitute the vlaues and get the answer -------------》 [STEP 2]

(x²+y²) (x²-y²)= x²-y² [FINAL ANSWER]

HENCE THE FINAL ANSWER IS X²-Y² BECAUSE THEY CANT BE SUBTRACTED

HOPE IT HELPS!!
