the RHS can be expressed as a square

[tall estuary]

what is RHS

[plush wraith]

right hand side

[tall estuary]

how so?

[plush wraith]

a^2 + b^2 + 2ab

can be expressed as a square

[tall estuary]

its not squared tho

its f(x + t)

[plush wraith]

right hand side

a^2 + b^2 + 2ab = (a + b)^2

[tall estuary]

oh sht

[plush wraith]

what could be a and b here

[tall estuary]

sqrt of f(x) and f(t)

[plush wraith]

yep

[tall estuary]

ok after I rewrite it what shall I do

Since $\sqrt{f(x + t)} = \sqrt{f(x)} + \sqrt{f(t)}$, first consider substituting $t = 0$ and find out the value of $f(0)$
