Jawaban:

${x}^{1} = - 1 \ {x}^{2} = 3$

Penjelasan dengan langkah-langkah:

$y = sqrt{3 + 2x - {x}^{2} }$

$0 = sqrt{3 + 2x - {x}^{2} }$

$sqrt{3 + 2x - {x}^{2} } = 0$

$3 + 2x - {x}^{2} = 0$

$- {x}^{2} + 2x + 3 = 0 \ {x}^{2} - 2x - 3 = 0$

${x}^{2} + x + 3x + 3 = 0 \ xx(x - 1) - 3(x + 1) = 0$

$(x + 1) times (x - 3) = 0 \ x + 1 = 0 \ x - 3 = 0$

$x = - 1 \ x = 3$

Semoga bisa membantu
