0 = 9 t - t^{3}

t = 0, t = - 3, t = 3

Solution steps

0 = 9 t - t^{3}

Switch sides

9 t - t^{3} = 0

Factor

9 t - t^{3} : - t (t + 3) (t - 3)

- t (t + 3) (t - 3) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

t = 0 or t + 3 = 0 or t - 3 = 0

Solve

t + 3 = 0 : t = - 3

Solve

t - 3 = 0 : t = 3

The solutions are

t = 0, t = - 3, t = 3

x^{4} + 3 = 84

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

- y (1 + y^{2}) = 0

(2 x + 3) (x + 2)^{2} = 4 (2 x + 3)

- x^{3} + 3 x^{2} + 62 x - 184 = 0
