Who introduced quadratic equations?

Hint: First, we will see the concept of the quadratic equation, and also, we will discuss who introduced the second-degree quadratic equation.
Since quadratic means second degree equation, which has at most degree power two terms in the given function or the polynomial too.

Complete step-by-step solution:
Quadratic equations are called second-degree equations. It means that it consists of at least one term which is squared. Because of this reason, it is known as a quad meaning square.
The general form of the quadratic equation is $a{x^2} + bx + c = 0$ where a, b, and c are numerical coefficients or constants and the value of x is the unknown.
One fundamental rule is that the value $a$ will never be zero. Because if $a = 0$ then we get $bx + c = 0$ but which is a degree one equation and known as the linear equations, thus the value of a will never zero.
Hence this quadratic method was first introduced by Rene Descartes in the publication named La Geometries and in the year of $1637$ .

Note: The standard form of the quadratic equation is by solving any of the quadratic values, suppose take $a{x^2} + bx + c = 0$ then the quadratic formula is $x = \dfrac{{ - b \pm \sqrt {{b^2} - 4ac} }}{{2a}}$ it was also known as the Sridharacharya formula to find the variable x and also called as the zeroes of the polynomial formula.
These equations constitute a significant part that is necessary to solve several kinds of the complicated mathematical problem.
In the real-life, they are used extensively, calculating the areas, speed, and other dimensions and also the zeroes of the polynomial.
To solve the quadratic equation we use the standard method, factoring method.
