x²- 16x + y²- 4y - 557 = 0 is the equation of the circle
The solutions to the given quadratic equation are as follows:
x = 1.10, x = 10.9.
<h3>What is a quadratic function?</h3>
A quadratic function is given according to the following rule:
The solutions are:
In which:
For this problem, the equation in item D is:
-x² + 12x - 12 = 0
x² - 12x + 12 = 0
Hence the coefficients are:
a = 1, b = -12, c = 12.
Then the solutions to the equation are found as follows:
- Delta = (-12)² - 4 x 1 x 12 = 96
- x1 = 0.5(12 + sqrt(96)) = 10.9
- x2 = 0.5(12 - sqrt(96)) = 1.10
The solutions are:
x = 1.10, x = 10.9.
