If we can discover a root of that factor, we can continue the process, reducing the degree each time, until we reach a. Quadratic Formula Calculator In algebra, quadratic equation is the formula where the highest exponent of a variable is 2. Quadratic equations are second degree polynomials having the power of 2

- A 4th degree polynomial has a maximum of 4 roots. Because the polynomial has integer coefficients, any irrational root requires its conjugate also be a root. Since 5-√3 is a root, the conjugate 5+√3 must also be a root. With 3 as a root, there's only *one* more possible root. We couldn't add another irrational root because we'd need *two.
- The first step in finding the solutions of (that is, the x-intercepts of, plus any complex-valued roots of) a given polynomial function is to apply the Rational Roots Test to the polynomial's leading coefficient and constant term, in order to get a list of values that might possibly be solutions to the related polynomial equation.

- Well, if you make each root into a factor, i.e. for root r you form the factor (x -r), then their product will be a 4th degree polynomial such that the 4 roots are 0. This means your polynomial will be: (x - 1)(x -1)(x - 2)(x - 0), which can be entered into the calculator just like that, if you need to graph it on the calculator
- If a polynomial with all rational coefficients, then if it has one irrational root, its conjugate will also be a root. So here, since we have a root of #sqrt2#, we also know that #-sqrt2# is a root. This goes the same for #2-sqrt3#.We know that #2+sqrt3# also must be a root. (Note these these four roots will give us a fourth degree polynomial.
