Question

solve this please by using formula

Answer 1

a = (a + b)^2

b = 8a^2- 8b^2

c = 16(a - b)^2

D = a^2 + b^2 + 2ab + 8a^2 - 8b^2 +16(a^2 + b^2 - 2ab

= 17a^2 + 17b^2 - 30ab + 8a^2 - 8b^2

= 25a^2 + 9 b^2 - 30ab

= (5a - 3b)^2

√D = 5a - 3b

X = 8b^2 - 8a^2 + 5a - 3b / 2a^2 + 2b^2 + 4ab

OR

X = 8b^2 - 8a^2 + 3b - 5a / 2a^2 + 2b^2 + 4ab
