If x + y = 2 and xy = 2, then find the value of x² + y².

$\color {red} </p><p>\Large \underline {\underline {To \: find \: :}}$

The value of x² + y²

$\color {red} </p><p>\Large \underline {\underline {Given \: :}}$

• x + y = 2
• xy = 2

$\color {red} </p><p>\Large \underline {\underline {We \: know \: :}}$

$(x + y) {}^{2} = {x}^{2} + 2xy + {y}^{2}$

$\color {red} </p><p>\Large \underline {\underline {Solution \: :}}$

$(x + y) {}^{2} = {x}^{2} + 2xy + {y}^{2}$

$(x + y) {}^{2} - 2xy = {x}^{2} + {y}^{2}$

Put the values here.

${2}^{2} - 2(2) = {x}^{2} + {y}^{2}$

$4 - 4 = {x}^{2} + {y}^{2}$

$0 = {x}^{2} + {y}^{2}$

$\implies$ So, the value of x² + y² is 0
