How far is the chord from the center of the circle? 43.

solving quadratic equations mixed worksheet with answers.

In this case, the equation does not have real roots. In this case, the equation has one real root. In this case, the equation has two distinct real roots. Because of its importance: $$b² - 4ac$$ is called the determinant of the quadratic equation $$ax² + bx + c = 0$$ The expression $$b² - 4ac$$ that appears in the quadratic formula under the square root plays an important role in solving quadratic equations. The roots x can be found by completing the square, $$ax^2 + bx + c = 0$$ $$x^2 + \frac$$ Quadratic Equation - from Wolfram MathWorld Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution.
