Question

x= a2 b2, у = ab
Find (a+b)

Answer 1

Step-by-step explanation:

Given:-

• x=a^2+b^2
• y=ab

To find:-

• a+b

Solution:-

We know that

$\\ \sf{:}\longrightarrow (a+b)^2=a^2+b^2+2ab$

$\\ \sf{:}\longrightarrow (a+b)^2=x+2(y)$

$\\ \sf{:}\longrightarrow a+b=\sqrt{x+2y}$

$\\ \sf{:}\longrightarrow a+b=\sqrt{x}+\sqrt{2}\sqrt{y}$
