roots

x^{4} - 4 x^{3} + 8 x^{2} - 16 x + 16

x = 2, x = 2 i, x = - 2 i

Solution steps

x^{4} - 4 x^{3} + 8 x^{2} - 16 x + 16

The roots are the intercepts with the x-axis

(y = 0)

x^{4} - 4 x^{3} + 8 x^{2} - 16 x + 16 = 0

Factor

x^{4} - 4 x^{3} + 8 x^{2} - 16 x + 16 : (x - 2)^{2} (x^{2} + 4)

(x - 2)^{2} (x^{2} + 4) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x - 2 = 0 or x^{2} + 4 = 0

Solve

x - 2 = 0 : x = 2

Solve

x^{2} + 4 = 0 : x = 2 i, x = - 2 i

The solutions are

x = 2, x = 2 i, x = - 2 i

- 1 = m^{3}

x^{4} + 6 x^{3} + 17 x^{2} + 22 x + 14 = 0

x^{3} - 4 x - 8 = 0

x^{3} - 3 x^{2} - 4 x + 12

2 x^{3} - 3 x^{2} - 32 x + 48 = 0
