Final answer:
The quadratic equation y = x² - 11x + 7 has two real solutions.
Step-by-step explanation:
The quadratic equation y = x² - 11x + 7 can be solved to find its roots. The equation is of the form ax² + bx + c = 0, where a = 1, b = -11, and c = 7. The quadratic formula can be used to find the roots of the equation:
x = (-b ± √(b² - 4ac)) / (2a)
Plugging in the values for a, b, and c, we get:
x = (-(-11) ± √((-11)² - 4(1)(7))) / (2(1))
Simplifying further, we have:
x = (11 ± √(121 - 28)) / 2
x = (11 ± √93) / 2
Therefore, the quadratic equation has two real solutions.
