- 5 x^{3} + 35 x - 30 = 0

x = 1, x = 2, x = - 3

Solution steps

- 5 x^{3} + 35 x - 30 = 0

Factor

- 5 x^{3} + 35 x - 30 : - 5 (x - 1) (x - 2) (x + 3)

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

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x - 1 = 0 or x - 2 = 0 or x + 3 = 0

Solve

x - 1 = 0 : x = 1

Solve

x - 2 = 0 : x = 2

Solve

x + 3 = 0 : x = - 3

The solutions are

x = 1, x = 2, x = - 3

x, y - 2 x^{4} y^{5} = - 1

s^{4} + 4 s^{3} + 6 s^{2} + 4 s + 1 = 0

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

x^{1000} = 0.9

x^{3} - 3 x^{2} - 10 x + 24 = 0
