When a number is multiplied by itself and 2 is added to it, the result is 227. What is the number?

Ede4ka [16]

Let number be x

$\leadsto \sf {x}^{2} + 2 = 227$

$\\ \\$

$\leadsto \sf {x}^{2} = 227 - 2$

$\\ \\$

$\leadsto \sf {x}^{2} = 225$

$\\ \\$

$\leadsto \sf {x} = \sqrt{225}$

$\\ \\$

$\leadsto \sf {x} = \sqrt{15 \times 15}$

$\\ \\$

$\leadsto \sf {x} = 15$

Number = 15
