How do you write a quadratic equation in Java?

Java program to find the roots of a quadratic equation
  1. Calculate the determinant value (b*b)-(4*a*c).
  2. If determinant is greater than 0 roots are [-b +squareroot(determinant)]/2*a and [-b -squareroot(determinant)]/2*a.
  3. If determinant is equal to 0 root value is (-b+Math.sqrt(d))/(2*a)

What is quadratic equation in Java?

The standard form of a quadratic equation is: ax2 + bx + c = 0. Here, a , b , and c are real numbers and a can’t be equal to 0. We can calculate the root of a quadratic by using the formula: x = (-b ± √(b2-4ac)) / (2a)

How do you find the roots of a polynomial in Java?

In the function, first, we check the value of a if it is 0 means it is not a quadratic equation. Then we calculate the discriminant and check whether it is greater than 0, equal to 0 or less than zero. Then we apply formula -b+sqrt(b2 -4ac)/2a and -b-sqrt(b2 -4ac)/2a and print the result.

What is polynomial C++?

Polynomial comes from two words: – “Poly” which means “many” and “nomial” means “terms”, which comprises many terms. Polynomial expression is an expression containing variables, coefficients and exponents, which only involves operations such as, addition, multiplication and subtraction of variable(s).
