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.
You substitute the value of the variable into the quadratic equation and evaluate the expression.
we study linear equation in other to know more about quadratic equation
Equations of the form z^4+az^2+a_0 are known as biquadratic equations. They are quartic equations. In general they can be solved by reducing them to a quadratic equation where x=z^2 is the variable. Then you can use the quadratic formula or factor. So plugging in x to the biquadratic giives us x^2+ax+a_0.
There is no quadratic equation that is 'linear'. There are linear equations and quadratic equations. Linear equations are equations in which the degree of the variable is 1, and quadratic equations are those equations in which the degree of the variable is 2.
radical equations have sq roots, cube roots etc. Quadratic equations have x2.
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.
Because it's part of the quadratic equation formula in finding the roots of a quadratic equation.
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.

Using the quadratic equation formula or completing the square
Quadratic equations are called quadratic because quadratus is Latin for "square"; in the leading term the variable is squared.
There are many equations that are neither linear nor quadratic. A simple example is a cubic equation, such as y = x3, or a logarithmic equation, such as y = ln(x).
You substitute the value of the variable into the quadratic equation and evaluate the expression.
