What is the vertex form of a quadratic equation?

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

How do you convert standard form to vertex form?

To convert from standard form $$y = ax^2 + bx + c$$ to vertex form, you can complete the square.

What is the axis of symmetry in a quadratic function?

The axis of symmetry is a vertical line that divides the parabola into two mirror images. It can be found using the formula $$x = -\frac{b}{2a}$$ .

What is the significance of the leading coefficient in a quadratic equation?

The leading coefficient (the coefficient of $$x^2$$ ) determines the direction of the parabola: if positive, it opens upwards; if negative, it opens downwards.

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

To solve using the quadratic formula, identify coefficients a, b, and c from the equation $$ax^2 + bx + c = 0$$ , then substitute them into $$x = \frac{{-b \pm \sqrt{{b^2 - 4ac}}}}{{2a}}$$ .

What is the relationship between the roots and the coefficients of a quadratic equation?

For a quadratic equation $$ax^2 + bx + c = 0$$ , the sum of the roots is $$-\frac{b}{a}$$ and the product of the roots is $$\frac{c}{a}$$ .

How do you check your solutions for a quadratic equation?

To check your solutions, substitute the values of x back into the original equation to see if they satisfy the equation.

What is the importance of rounding in solving quadratic equations?

Rounding is important in solving quadratic equations to provide a concise and accurate answer, especially when dealing with irrational numbers.
