Heya

Second step of solution in detail is here :-

To understand how second step comes, we have to understand the first step, which is as follows :-

∆ = √(x/2 + y) × (x/2 + y) × x/2 × x/2

We can also write this as -

∆ = √(x/2 + y) × √(x/2 + y) × √(x/2 × x/2)

∆ = √(x/2 + y) + √(x/2 + y) + √(x/2)²

∆ = √(x/2)² × √(x/2 + y) × (x/2 + y)

∆ = [(x/2)²]½ × √(x/2 + y) × (x/2 + y)

{After removing the square root, the number has the power ½}

∆ = x/2 × √(x/2 + y) × (x/2 + y)

Hope this helps you.
