Question

(x-3)²- (y+1)² = 9
y = -1

Answer 1

Х²-6х+9-у²+2у+1=9

Х=0; 6 подставь их

Answer 2

${(x - 3)}^{2} - {(y + 1)}^{2} = 9$

при $y = - 1$,

${(x - 3)}^{2} - {( - 1 + 1)}^{2} = 9$

${(x - 3)}^{2} - {0}^{2} = 9$

${(x - 3)}^{2} = 9$

${x}^{2} - 6x + 9 = 9$

${x}^{2} - 6x + 9 - 9 = 0$

${x}^{2} - 6x = 0$

$x(x - 6) = 0$

$x_1 = 0$,

$x - 6 = 0$

$x_2 = 6$
