Aright triangle is shown below whose sides are 2x, x2 - 1, and x2 + 1.

(a)
prove the identity (2x)2 + (x2 - 1)2 = (x2 + 1)2
for x > 1.
x2 +1
.12-1

 PROVED

Step-by-step explanation:

The sides of the given right triangle are :

Now here, To show:    .... (1)

Now, by ALGEBRAIC IDENTITY:

So here, similarly

Now, substituting the value on Left side of (1) , we get :

 ...... (a)

Also, the right side of (1) is:

 ... (b)

from(a) and (b) we see that
