x^{4} + 6 x^{2} - 6 x^{3} - 6 x + 5 = 0

x = 1, x = 5, x = i, x = - i

Solution steps

x^{4} + 6 x^{2} - 6 x^{3} - 6 x + 5 = 0

Write in the standard form

a_{n} x^{n} + \dots + a_{1} x + a_{0} = 0

x^{4} - 6 x^{3} + 6 x^{2} - 6 x + 5 = 0

Factor

x^{4} - 6 x^{3} + 6 x^{2} - 6 x + 5 : (x - 1) (x - 5) (x^{2} + 1)

(x - 1) (x - 5) (x^{2} + 1) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x - 1 = 0 or x - 5 = 0 or x^{2} + 1 = 0

Solve

x - 1 = 0 : x = 1

Solve

x - 5 = 0 : x = 5

Solve

x^{2} + 1 = 0 : x = i, x = - i

The solutions are

x = 1, x = 5, x = i, x = - i

x^{3} - 49 x = 0

D, 6 b + r b = D^{3}

x^{3} - 5 x + 3 = 0

x^{3} - 2 x^{2} - 2 = 0

x = x^{4}
