Question

Raizes da equacao (x-3)²=289

Answer 1

$\large\sf{}\left(x - 3\right)^{2} = 289 \\ \\ \large\sf{}x - 3 = \pm \: 17 \\ \\\large\sf{}x - 3 = - 17 \\ \large\sf{}x - 3 = 17 \\ \\ \large\sf{}x = - 14 \\ \large\sf{}x = 20 \\ \\ \large\sf{} x_{1} = - 14 \\ \large\sf{} x_{2} = 20 \\ \\ \\{\large\boxed{\boxed{  { \large \sf x_{1} = - 14 }}}} \\ {\large\boxed{\boxed{  { \large \sf x_{2} = 20}}}}$
