x^{4} - x^{3} + x = 1

x = 1, x = - 1, x = \frac{1}{2} + i \frac{3}{2}, x = \frac{1}{2} - i \frac{3}{2}

Solution steps

x^{4} - x^{3} + x = 1

Move

1

to the left side

x^{4} - x^{3} + x - 1 = 0

Factor

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

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

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

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

Solve

x - 1 = 0 : x = 1

Solve

x + 1 = 0 : x = - 1

Solve

x^{2} - x + 1 = 0 : x = \frac{1}{2} + i \frac{3}{2}, x = \frac{1}{2} - i \frac{3}{2}

The solutions are

x = 1, x = - 1, x = \frac{1}{2} + i \frac{3}{2}, x = \frac{1}{2} - i \frac{3}{2}

- 2 x (x^{2} - 10) (x^{2} + 4) = 0

y^{4} + y^{2} - 2 = 0

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

x^{3} - 7 x^{2} + x - 7 = x^{2} + 1

3 x^{4} - 27 x^{2} = 0
