WebThe typical approach of solving a quadratic equation is to solve for the roots x = − b ± b 2 − 4 a c 2 a Here, the degree of x is given to be 2 However, I was wondering on how to solve an equation if the degree of x is given to be n. For example, consider this equation: a 0 x n + a 1 x n − 1 + ⋯ + a n = 0 polynomials Share Cite WebThe only way to take the square root of negative numbers is with imaginary numbers, or complex numbers, which results in imaginary roots, or zeroes. They always come in conjugate pairs, since taking the square root has that + or - along with it. 3 comments ( 46 votes) Upvote Flag Show more... Gabrielle 7 years ago So why isn't x^2= -9 an answer?
Web3 You need to solve the equation x 5 + 2 x 3 + x − 1 = y for x. Unfortunately, such quintic equations are known to have no closed-form solution in general, and this one does not escape the rule. Anyway, there is a little backdoor, as a quintic can be (after painful computation) reduced to the form known as Bring Quintic Form x 5 − x − a = 0.
WebA cubic equation is an algebraic equation of third-degree. The general form of a cubic function is: f (x) = ax 3 + bx 2 + cx 1 + d.
