Answer 2

$\huge{{\huge{\boxed{\huge{\red\star\mathfrak\purple{\large{\underline{\underline{Question:-}}}}}}}}}$

x+y=12

xy=32

$\red{ \boxed{ \mathfrak \pink{To \: find:x {}^{2} + y {}^{2} }}}$

$\huge{{\huge{\boxed{\huge{\orange\star\mathfrak\red{\large{\underline{\underline{ Solution:-}}}}}}}}}$

(x+y)²= x²+2xy+y²

⟹(12)²= x²+y²+2xy

⟹144=x²+y²+2×32

⟹144= 64+ x²+y²

⟹x²+y²=144-64

$\huge \boxed{ \bold \red{⟹x {}^{2} +y {}^{2} = 80 }}$
