Solve −2x2 +3x − 9 = 0
luda_lava [24]
-2x^2 + 3x - 9 = 0
The quadratic is not factorable so quadratic formula must be used.
x = (-b + - √(b^2 - 4ac))/2a
a = -2, b = 3, c = -9
x = (-3 + - √(9 - 4*-2*-9))/-4
x = (-3 + - √(-63))/-4
x = -3 + - 3i√7
     --------------
           -4
x = 3 + 3i√7            x = 3 - 3i√7
    ------------                ------------

motikmotik

Answer:

x1 = 0.16203454

x2= 0.04843273+0.06766624j

x3= 0.04843273-0.06766624j

Step-by-step explanation:

The better way to obtain roots of a polynomial when is not easy to analytically factorize is to use software as Matlab or Python. Use the following code in Python

import numpy as np

pol=np.array([1,-0.2589, 0.02262,-0.001122])

roots=np.roots(pol)

print(roots)
