A quadratic equation is an equation where a quadratic polynomial is equal to zero. It can be written as ax^2+bx+c=0 where a,b,c are the coefficients and x is the variable. A quadratic equation has always two complex solutions for x given by the formula x=-b/2a+sqrt(b^2-4ac)/2a and x=-b/2a-sqrt(b^2-4ac)/2a. Examples of quadratic equations are x^2+x-2=0, 5x^2+6x=0, x^2+1=0 etc.

You know an equation is quadratic by looking at the degree of the highest power in the equation. If it is 2, then it is quadratic. so any equation or polynomial of the form: ax2 +bx+c=0 where a is NOT 0 and a, b and c are known as the quadratic coefficients is a quadratic equation.

The quadratic formula is used to solve the quadratic equation. Many equations in which the variable is squared can be written as a quadratic equation, and then solved with the quadratic formula.

No. [ y = 4x2 ] is a quadratic equation.

A quadratic equation.

an equation has an equals sign.

The graph (on Cartesian coordinates) of a quadratic equation is a parabola.

It is still called a quadratic equation!

There are two degrees to a quadratic equation, as the x2 term is present. General form of a quadratic equation: Ax2+Bx+C

A quadratic equation normally has 2 solutions and can be solved by using the quadratic equation formula.

That depends on the equation.

Using the quadratic equation formula is a method of solving quadratic equations.

The roots of the quadratic equation are the x-intercepts of the curve.

It is used to solve quadratic equations that cannot be factored. Usually you would factor a quadratic equation, identify the critical values and solve, but when you cannot factor you utilize the quadratic equation.

Yes. You can calculate the two roots of a quadratic equation by using the quadratic formula, and because there are square roots on the quadratic formula, and if the radicand is not a perfect square, so the answer to that equation has decimal.

There are an infinite number of different quadratic equations. The quadratic formula is a single formula that can be used to find the pair of solutions to every quadratic equation.

Simply learn and use the quadratic equation formula.

By using the quadratic equation formula

It is finding the values of the variable that make the quadratic equation true.

x*2+4x+8= 0 is a quadratic equation

By using the quadratic equation formula or by completing the square

Because it's part of the quadratic equation formula in finding the roots of a quadratic equation.
