What is a quadratic equation?

A quadratic equation is a polynomial equation of the form ax^2 + bx + c = 0, where "a," "b," and "c" are constants, and "x" represents the variable. Quadratic equations are second-degree equations that can have one, two, or no real solutions, depending on the values of the coefficients. They can be graphed as parabolic curves and are commonly used in mathematics and physics to model various real-world situations.

How many solutions can a quadratic equation have?

A quadratic equation can have zero, one, or two solutions.

What is the general form of a quadratic equation?

The general form of a quadratic equation is written as ax^2 + bx + c = 0, where 'a', 'b', and 'c' are coefficients, and 'x' is the variable.

How do you determine the vertex of a quadratic equation?

To determine the vertex of a quadratic equation in the form of y = ax^2 + bx + c, you can use the formula x = -b / (2a) to find the x-coordinate of the vertex. Once you have found the x-coordinate, plug it back into the equation to find the y-coordinate of the vertex. The vertex of the quadratic equation is expressed as (x, y).

What is the discriminant of a quadratic equation?

The discriminant of a quadratic equation is a value that can be calculated from the coefficients of the equation (the numbers in front of the x^2, x, and constant term). It is used to determine the nature of the roots of the quadratic equation. If the discriminant is positive, the equation has two distinct real roots. If it is zero, the equation has one real root (a repeated root). If the discriminant is negative, the equation has no real roots (complex roots).

How do you solve a quadratic equation using factoring?

To solve a quadratic equation using factoring, follow these steps: 1. Write the equation in standard form ax^2 + bx + c = 0. 2. Factor the quadratic expression on the left side of the equation. 3. Set each factor equal to zero and solve for the values of x. These solutions will be the roots of the quadratic equation.

What is the quadratic formula?

The quadratic formula is a formula used to find the solutions (or roots) of a quadratic equation of the form ax^2 + bx + c = 0, where a, b, and c are constants, and a ? 0. The formula is x = (-b ± ?(b^2 - 4ac)) / 2a, where ± represents both the positive and negative values of the square root. This formula helps solve quadratic equations by providing the values of x where the equation equals zero.

How do you find the axis of symmetry of a quadratic equation?

To find the axis of symmetry of a quadratic equation in the form of y = ax² + bx + c, you can use the formula x = -b / 2a. The axis of symmetry represents the line that divides the parabola into two equal halves, and it is a vertical line passing through the vertex of the parabola. By calculating x = -b / 2a, you can determine the x-coordinate of the vertex and hence find the axis of symmetry.

Can a quadratic equation have imaginary solutions?

Yes, a quadratic equation can have imaginary solutions. This occurs when the discriminant of the quadratic equation, (b^2 - 4ac), is negative. In this case, the solutions are complex numbers with a real part and an imaginary part.

How do you graph a quadratic equation?

To graph a quadratic equation, first rearrange it in the standard form, y = ax^2 + bx + c. Next, determine the vertex of the parabola using the formula x = -b/(2a) and substitute this x-value into the equation to find the y-value. Plot the vertex, then use the axis of symmetry x = -b/(2a) to find additional points on either side of the vertex symmetrically. Lastly, connect the points smoothly to form a parabolic curve.
