Find all complex solutions of 3x 2+x+4 0
WebJan 23, 2016 · The real trick here is finding the remaining 4 complex roots. Since x = 2 is a root, (x − 2) is a factor of the quintic. The remaining roots can be found through solving the remaining quartic: x5 −32 x − 2 = x4 + 2x3 + 4x2 + 8x + 16 We want to solve for x: x4 +2x3 +4x2 +8x +16 = 0 Webthe discriminant is: Δ = b2 − 4ac. The discriminant can be used to characterize the solutions of the equation as: 1) Δ > 0 two separate real solutions; 2) Δ = 0 two coincident real solutions (or one repeated root); 3) Δ < 0 no real solutions. For example: x2 −x −2 = 0. Where: a = 1, b = −1 and c = −2.

WebTo find the roots factor the function, set each facotor to zero, and solve. The solutions are the roots of the function. What is a root function? A root is a value for which the function equals zero. The roots are the points where the function intercept with the x-axis; What are complex roots? Complex roots are the imaginary roots of a function. WebOct 19, 2015 · You have to change it a bit to account for the roots of negative unity. EDIT: Complete solution follows: x 7 + 1 = 0 or, ( x + 1) ( x 6 − x 5 + x 4 − x 3 + x 2 − x + 1) = 0 This implies your equation has exactly 1 real root and 3 pairs of complex conjugate roots. Hence now I can write x 7 + 1 = 0 or, x 7 = − 1 or,
