The calculator, helps you finds the roots of a second degree polynomial of the form ax^2+bx+c=0 where a, b, c are constants, a\neq 0.This calculator is automatic, which means that it outputs solution with all steps on demand.
A quadratic equation is any equation that can be written as \(ax^2+bx+c=0\), for some numbers \(a\), \(b\), and \(c\), where \(a\) is nonzero. The quadratic formula is one method of solving this type of question. Below, we will look at several examples of how to use this formula and also see how to work with it when there are complex solutions.
The quadratic x2 +2x+3 = 0 has no real solutions, so the only solution to the cubic equation is obtained by putting x− 1 = 0, giving the single real solution x = 1. The graph y = x 3 +x 2 +x− 3 is shown in Figure 4.
Substitute the coefficients into the quadratic equation and solve for x. Top. Solving Equations Containing x 3, x 4, etc. At times, you will have problems involving equilibrium expressions with the variable "x" raised to a power "n". x n = a number. With the aid of a calculator there are two ways you can go about solving for x. Using logarithms
After substituting this in to the area formula, we get . Since we want to find the maximum area, we can find the maximum of this quadratic function which will give us the maximum width. Letting b = 40 and a = -2, we get 10 to be the width. Plugging 10 into the equation gives l = 20. Thus our . maximum area is 200 feet2.
