x^{3} - 3 x = 2

x = - 1, x = 2

Solution steps

x^{3} - 3 x = 2

Move

2

to the left side

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

Factor

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

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

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x + 1 = 0 or x - 2 = 0

Solve

x + 1 = 0 : x = - 1

Solve

x - 2 = 0 : x = 2

The solutions are

x = - 1, x = 2

(1 + \frac{6.5}{100}) = (1 + x)^{4}

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

(x + 1) (x^{2} - 4) = (x + 1) (x - 4)

z^{5} - 2 = 0

x^{3} - 5 x^{2} - 9 x + 45 = 0
