Just enter the factors a, b and c below, and press 'Get Results' Your Equation: Solution 1: Solution 2: Discriminant: Note: Is it Quadratic Only if it can be put in the form ax2 + bx + c 0, and a is not zero.
This is the main formula that determines a quadratic equation. Quadratic Equation Solver If you have an equation of the form 'ax2 + bx + c 0', we can solve it for you.

For that, you need to use something like std::complex which is actually capable of storing complex numbers inside it.īelow is your code modified to utilize std::complex and will properly print the real and imaginary part separately for square roots of negative real numbers instead of simply returning nan as it did before.The Quadratic Formula: How to Solve a Quadratic Equation? Ordinary floating-point types like double which usually follow the IEEE-754 standard are not capable of representing complex numbers. In actual math, square roots of negative numbers result in complex numbers. Make sure that a 1 (if a 1, multiply through the equation by before. The quadratic formula is used to find the roots of a quadratic. Solving Quadratic Equations Put the equation into the form ax 2 + bx c. The first step to factoring an equation is to move all of the terms to one side of. For equations with real solutions, you can use the graphing tool to visualize the solutions. 1.Combine all of the like terms and move them to one side of the equation. The Quadratic Formula Calculator finds solutions to quadratic equations with real coefficients. It also raises the FE_INVALID floating point exception which you can verify after calling the std::sqrt() function using std::fetestexcept(FE_INVALID). The quadratic formula is a mathematical equation that is written in the form ax2+bx+c0. Step 1: Enter the equation you want to solve using the quadratic formula. Std::sqrt() in the header expects its argument to be a positive number, in case it isn't, it will return nan which is what you are facing.
