Respuesta:
estos puntos (5,-4) y (-7,-4)
Explicación paso a paso:
[tex] {(10)}^{2} = {( - 4 - 4)}^{2} + {(x + 1)}^{2} [/tex]
[tex]100 = {( - 8)}^{2} + {x}^{2} + 2x + 1[/tex]
[tex]100 = 65 + {x}^{2} + 2x[/tex]
[tex] {x}^{2} + 2x - 100 + 65 = 0[/tex]
[tex] {x}^{2} + 2x - 35 = 0[/tex]
[tex](x - 5)(x + 7) = 0[/tex]
[tex]x1 = 5[/tex]
[tex]x2 = - 7[/tex]
