решите уравнения по формуле
[tex]g = b {}^{2} - 4ac[/tex]
[tex]x 1 = \frac{ - b - \sqrt{g} }{2a} [/tex]
[tex]x2 = \frac{ - b + \sqrt{g} }{ 2a} [/tex]

1)
[tex](x - 3) { }^{2} + (x + 4) {}^{2} - (x - 5) {}^{2} = 17x + 24[/tex]
2)
[tex](x + 5) {}^{2} + (x - 2) { }^{2} + (x - 7)(x + 7) = 11x + 80[/tex]
