Quadratic Equations

Quadratic equations are essentially second-degree polynomials that consist of three different coefficients. They are typically written in the format of ax² + bx + c = 0. The methods employed for finding solutions include factorization, the quadratic formula, or the technique of completing the square. The graph of a quadratic equation takes the shape of a parabola, with the vertex and axis of symmetry being calculable.

Quadratic Formula

Find the roots of the quadratic equation \(2x^2 - 5x + 2 = 0\)

Solving by Factoring

Solve the quadratic equation \(3x^2 - 5x - 2 = 0\) by factoring.

Solve by Completing the Square

Solve the quadratic equation \(2x^2 - 6x - 8 = 0\) by completing the square.

Finding the Perfect Square Trinomial

Find the perfect square trinomial for the quadratic equation \(y = x^2 + 4x + c\), and determine the value of \(c\).

Finding the Quadratic Equation Given the Solution Set

Find the quadratic equation whose solutions are \(2\) and \(-3\).

Finding a,b, and c in the Standard Form

NASA launches a rocket at $t=0$ seconds. Its height, in meters above sea-level, as a function of time is given by $h(t)=-4.9 t^{2}+310 t+157$. Assuming that the rocket will splash down into the ocean, at what time does splashdown occur? The rocket splashes down after seconds. How high above sea-level does the rocket get at its peak? The rocket peaks at meters above sea-level.

Finding the Discriminant

Consider the quadratic equation \(x^2 - 6x + 5 = 0\). Find the discriminant of the quadratic equation.

Finding the Quadratic Constant of Variation

Given the quadratic equation \(x^2 + 5x + k = 0\) where \(k\) is the constant of variation. The two roots of the equation are 1 and 4. Find the value of \(k\).
