Ответ:
\[y = x^{2} + px + 35;\ \ \ \ \ (5;0).\]
\[25 + 5p + 35 = 0\]
\[5p + 60 = 0\]
\[5p = - 60\]
\[p = - 12\]
\[y = x^{2} - 12x + 35\]
\[x = \frac{12}{2} = 6\]
\[Ответ:\ \ p = - 12;\ \ x = 6.\]
\[y = x^{2} + px + 35;\ \ \ \ \ (5;0).\]
\[25 + 5p + 35 = 0\]
\[5p + 60 = 0\]
\[5p = - 60\]
\[p = - 12\]
\[y = x^{2} - 12x + 35\]
\[x = \frac{12}{2} = 6\]
\[Ответ:\ \ p = - 12;\ \ x = 6.\]
