x^{3} - 3 x^{2} - 50 = 0

x = 5, x = - 1 + 3 i, x = - 1 - 3 i

Solution steps

x^{3} - 3 x^{2} - 50 = 0

Factor

x^{3} - 3 x^{2} - 50 : (x - 5) (x^{2} + 2 x + 10)

(x - 5) (x^{2} + 2 x + 10) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x - 5 = 0 or x^{2} + 2 x + 10 = 0

Solve

x - 5 = 0 : x = 5

Solve

x^{2} + 2 x + 10 = 0 : x = - 1 + 3 i, x = - 1 - 3 i

The solutions are

x = 5, x = - 1 + 3 i, x = - 1 - 3 i

72 x^{4} - x^{2} - 1 = 0

(1 + x)^{5} = 1.24

6 x^{9} - 72 x^{7} - 7 x^{2} + 96 x - 63 = 0

- x^{3} - 13 x^{2} - 12 x + 10 = 0

x^{4} + 10 x^{2} - 11 = 0
