Introduction. This unit is about how to solve quadratic equations. A quadratic equation is one which must contain a term involving x2 e.g. 3x2
of the quadratic polynomial ax2 + bx + c. • Finding the roots of a quadratic equation by the method of factorisation : If we can factorise the quadratic
are 2 and -3. 1.7 Methods of Solving Quadratic Equation: There are three methods for solving a quadratic equation: i). By factorization.
use properties of cube roots of unity to solve appropriate problems. find the relation between the roots and the coefficients of a quadratic equation. ➤ find
A quadratic polynomial expression equated to zero becomes a quadratic equation and the values of x which satisfy the equation are called roots/ zeros of the

Is the quartic equation a quadratic equation?
But then the quartic is a quadratic equation in u2, u4+Au2+C= 0, which can be solved by two applications of the quadratic formula. Chapter 4 Field Extensions and Root Fields 4.1 Motivation for Field Theory
Who invented the quartic formula?
After Ferrari found a quartic formula, mathematicians tried to find formulas for higher degree equations. In the late 1700’s, this work was taken on by Lagrange (who also created the metric system during the French Revolution).
Which axis corresponds to a quadratic equation ax2+bx+c=0?
The horizontal line, thexaxis, corresponds to points on the graph wherey= 0. So points wherethe graph touches or crosses this axis correspond to solutions of ax2+bx+c=0. In Figure 2, the graph in (a) never cuts or touches the horizontal axis and so this correspondsto a quadratic equationax2+bx+c= 0 having no real roots.
What is the generic equation of degree n?
n= 0 is called the generic equation of degree n. The quadratic formula gives a solution of the generic equation of degree 2: Solution of X2+ a 1X+ a
