t^{3} - 9 t = 0

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

Solution steps

t^{3} - 9 t = 0

Factor

t^{3} - 9 t : 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

25 x^{4} + 16 = 41 x^{2}

3 x^{3} + 15 x^{2} - 2 x = 10

(x + 4) \cdot (- 4 x^{2} + 4 x - 1) = 0

n^{4} (n + 5) - 2 (5 + 7 n) = - 70

z^{4} = 6 z^{2} + 7
