p^{3} - 49 p = 0

p = 0, p = - 7, p = 7

Solution steps

p^{3} - 49 p = 0

Factor

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

p (p + 7) (p - 7) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

p = 0 or p + 7 = 0 or p - 7 = 0

Solve

p + 7 = 0 : p = - 7

Solve

p - 7 = 0 : p = 7

The solutions are

p = 0, p = - 7, p = 7

8 = x^{4} - 2 x^{2}

9.1 = x^{3} - 2 x + 5

25 b^{2} + 35 b^{4} = 45 b^{5}

12 x^{3} + 13 x^{2} + x = 0

2 x^{3} - 5 x^{2} + 6 x + 27 = 0
