Find the products:((5/6) a2+2) ((5/6) a2+2)

Answer»

Given that ((5/6) a2+2) ((5/6) a2+2)

But we can write the given expression as

((5/6) a2+2) ((5/6) a2+2)= ((5/6) a2+2)2

But we have (a + b)2=a2+2ab+b2

On applying above identity in the given expression we get,

((5/6) a2+2)2= ((5/6) x)2+2 ((5/6)) (2) + (2)2

((5/6) a2+2)2= (25/36) x2+ (10/3) x + 4y2
