(x + 1) (- 3 x^{2} + 9 x + 30) = 0

x = - 1, x = - 2, x = 5

Solution steps

(x + 1) (- 3 x^{2} + 9 x + 30) = 0

Factor

(x + 1) (- 3 x^{2} + 9 x + 30) : - 3 (x + 1) (x + 2) (x - 5)

- 3 (x + 1) (x + 2) (x - 5) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x + 1 = 0 or x + 2 = 0 or x - 5 = 0

Solve

x + 1 = 0 : x = - 1

Solve

x + 2 = 0 : x = - 2

Solve

x - 5 = 0 : x = 5

The solutions are

x = - 1, x = - 2, x = 5

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

x, 2 f - f (\frac{1}{x}) = ln (x^{3})

x^{102} - 5 = 2

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

a, a^{5} + b^{5} = 4806
