x^{3} + 9 x + 10 = 0

x = - 1, x = \frac{1}{2} + i \frac{39}{2}, x = \frac{1}{2} - i \frac{39}{2}

Solution steps

x^{3} + 9 x + 10 = 0

Factor

x^{3} + 9 x + 10 : (x + 1) (x^{2} - x + 10)

(x + 1) (x^{2} - x + 10) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x + 1 = 0 or x^{2} - x + 10 = 0

Solve

x + 1 = 0 : x = - 1

Solve

x^{2} - x + 10 = 0 : x = \frac{1}{2} + i \frac{39}{2}, x = \frac{1}{2} - i \frac{39}{2}

The solutions are

x = - 1, x = \frac{1}{2} + i \frac{39}{2}, x = \frac{1}{2} - i \frac{39}{2}

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

(x^{2} - 9) (x^{2} + 1) = 0

x^{4} + 6 x^{3} - 9 x^{2} - 54 x + 81 = 0

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

x^{3} + 2 x^{2} - 36 x - 72 = 0
