What is the quadratic formula used to solve equations of the form $$ax^2 + bx + c = 0$$ ?

The quadratic formula is $$x = \frac{-b \pm \\sqrt{b^2 - 4ac}}{2a}$$ .

What is the standard form of a quadratic equation?

The standard form is $$y = ax^2 + bx + c$$ .

How do you complete the square for a quadratic equation?

To complete the square, rearrange the equation to isolate the constant, then add and subtract the square of half the coefficient of $$x$$ .

What is the formula for the height of a projectile at time t?

The height is given by $$h(t) = h_0 + v_0t - \frac{1}{2}gt^2$$ , where $$h_0$$ is the initial height, $$v_0$$ is the initial velocity, and $$g$$ is the acceleration due to gravity.

What is the discriminant of a quadratic equation and what does it indicate?

The discriminant is $$D = b^2 - 4ac$$ . It indicates the nature of the roots: if D > 0, two real roots; D = 0, one real root; D

What is the formula for the time to reach maximum height for a projectile?

The time to reach maximum height is given by $$t = \frac{v_0}{g}$$ , where $$v_0$$ is the initial velocity and $$g$$ is the acceleration due to gravity.

How do you solve a quadratic equation by using the quadratic formula?

Substitute the values of $$a$$ , $$b$$ , and $$c$$ into the quadratic formula $$x = \frac{-b \\pm \\sqrt{b^2 - 4ac}}{2a}$$ and simplify.

What is the vertex form of a quadratic function?

The vertex form is $$y = a(x - h)^2 + k$$ , where $$(h, k)$$ is the vertex of the parabola.
