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

x = 0, x = 7, x = - 9

Solution steps

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

Factor

63 x - 2 x^{2} - x^{3} : - x (x - 7) (x + 9)

- x (x - 7) (x + 9) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x - 7 = 0 or x + 9 = 0

Solve

x - 7 = 0 : x = 7

Solve

x + 9 = 0 : x = - 9

The solutions are

x = 0, x = 7, x = - 9

x^{5} = 1024

4 x^{5} - x^{3} - 4 x^{2} + 1 = 0

x^{4} - 5 x^{2} - 44 = 0

(x - 5)^{3} = 1

(x - 5)^{4} - (5 - x)^{2} = 0
