How you solve an equation that doesn't factor is to plug a quadratic equation's format; ax2+bx+c into the quadratic formula which is x=-b+square root to (b2-4ac)/2a.

There are different methods of using quadratic functions depending on the equation.

Using the quadratic equation formula:- x = 3.795831523 or x = -5.795831523

With great difficulty because it is not a quadratic equation or even a quadratic expression.

at first the first person to solve the quadratic equation is from the middle kingdom of Egypt. Greeks were also able to solve the quadratic equation but that was on the unproper way. Greeks were able to solve the quadratic equation by geometric method or equlid's method. equlid's method contains only three quadratic equation. dipohantus have also solved the quadratic equations but he have solved by giving only two roots any they both were only of positive signs.After that arbhatya also gave the two formulas for quadratic equation but the bentaguptahave only accepted only one of them after theat some of the Indian mathematican have also solved the quadratic equation who gave the proper definations and formula and in this way quadratic equation have been formed.

Graphically might be the simplest answer.

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.

By using the quadratic equation formula

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.

The quadratic formula cannot be used to solve an equation if the coefficient of the equation's x2-term is 0.

The quadratic formula cannot be used to solve an equation if the coefficient of the equation x square term is what?

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

The most straightforward way to do this is to use the quadratic equation.

The quadratic formula can be used to solve an equation only if the highest degree in the equation is 2.

a is the coefficient of the x2 term. If is a = 0, then it is no longer a quadratic - it is just a linear equation, and the quadratic formula will not work to solve it.

Pros: There are many real life situations in which the relationship between two variables is quadratic rather than linear. So to solve these situations quadratic equations are necessary. There is a simple equation to solve any quadratic equation. Cons: Pupils who are still studying basic mathematics will not be told how to solve quadratic equations in some circumstances - when the solutions lie in the Complex field.
