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

x = 6, x = - 3, x = 3

Solution steps

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

Factor

x^{3} - 6 x^{2} - 9 x + 54 : (x - 6) (x + 3) (x - 3)

(x - 6) (x + 3) (x - 3) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x - 6 = 0 or x + 3 = 0 or x - 3 = 0

Solve

x - 6 = 0 : x = 6

Solve

x + 3 = 0 : x = - 3

Solve

x - 3 = 0 : x = 3

The solutions are

x = 6, x = - 3, x = 3

(x^{2} + 4)^{2} = 0

e = (m^{8}) 3 m^{21}

3 x^{3} + 4 x^{2} - 7 x + 2 = 0

2 x^{2} + 15 x = x^{3}

x^{8} + 3 x^{4} = 4
