9 x^{2} - 14 x - x^{3} = 0

x = 0, x = 2, x = 7

Solution steps

9 x^{2} - 14 x - x^{3} = 0

Factor

9 x^{2} - 14 x - x^{3} : - x (x - 2) (x - 7)

- x (x - 2) (x - 7) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x - 2 = 0 or x - 7 = 0

Solve

x - 2 = 0 : x = 2

Solve

x - 7 = 0 : x = 7

The solutions are

x = 0, x = 2, x = 7

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

2 x^{3} + 49 = x^{2} + 98 x

4 x^{3} = 2 x^{2}

x (2 x - 1) (x + 4) = 0

x^{4} - 15 x^{2} + 56 = 0
