How to Find Roots Calculator?
A polynomial with a degree of 1 is known as a linear polynomial
A polynomial with a degree of 2 is known as a quadratic polynomial.
A polynomial with a degree of 3 is known as a cubic polynomial.
A polynomial with a degree of 4 is known as a quartic polynomial.
A polynomial with a degree of 5 is known as a quintic polynomial.
A polynomial with a degree(n) greater than 5 is known as an nth degree polynomial.
A polynomial with any degree equates it to zero and finds the roots of a given polynomial.
The word "Quadratic" is derived from the word "Quad" which means square. In other words, a quadratic equation is an “equation of degree 2”
An equation of the form ax2 + bx + c = 0, where a ≠ 0 is called a quadratic equation and a, b, c are coefficients of the quadratic equation.
To solve the quadratic equation, we need to find the roots of a given quadratic equation, we use the discriminant formula given by:
\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)
Similarly, you can try the calculator to find the roots for the following:
- 2x3 + x - 3 = 0
- x4 + 10x3 - 5x - 11 = 0
