WebSolving a fourth degree equation (quartic equation) (1) 1. Using the substitution we get the depressed equation (2), where 2. If , we will solve If , then this equation always has a positive root The roots of the original quartic equation (1) can be obtained by the formulas 3. If q = 0, then the reduced equation (2) becomes a biquadratic equation Webx = 2 and x = 4 are the two zeros of the given polynomial of degree 4. Because x = 2 and x = 4 are the two zeros of the given polynomial, the two factors are (x - 2) and (x - 4). To find other factors, factor the quadratic expression which has the coefficients 1, 8 and 15. That is, x2 + 8x + 15. x2 + 8x + 15 = (x + 3) (x + 5)

WebJan 17, 2015 · I need to solve a 4th degree equation with python. For this I'm using the sympy module. When I run the script, sympy returns the 4 solutions of the equation as complex numbers (see output), while, in fact, all of them are real. What is making sympy return the wrong answer? WebApr 17, 2024 · I'm assuming here that x is integer because integer solution would be easier to find and work out. x 4 + x 3 + x = 3 x 3 ( x + 1) + x = 3 x 3 ( x + 1) + ( x + 1) = 4 ( x 3 + 1) ( x + 1) = 4 Here, ( x 3 + 1) ( x + 1) = 2 × 2 Thus, by comparing: x 3 + 1 = 2, and, x + 1 = 2. So, x = 1 is the only integral answer.
