x^{3} - 49 x = 0

x = 0, x = - 7, x = 7

Solution steps

x^{3} - 49 x = 0

Factor

x^{3} - 49 x : x (x + 7) (x - 7)

x (x + 7) (x - 7) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x + 7 = 0 or x - 7 = 0

Solve

x + 7 = 0 : x = - 7

Solve

x - 7 = 0 : x = 7

The solutions are

x = 0, x = - 7, x = 7

D, 6 b + r b = D^{3}

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

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

x = x^{4}

z^{6} = - 1
