9 x^{8} - 72 x^{7} = 0

x = 0, x = 8

Solution steps

9 x^{8} - 72 x^{7} = 0

Factor

9 x^{8} - 72 x^{7} : 9 x^{7} (x - 8)

9 x^{7} (x - 8) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x - 8 = 0

Solve

x - 8 = 0 : x = 8

The solutions are

x = 0, x = 8

x^{3} - 2 x^{2} - 19 x + 20 = 0

x^{3} - 64

x^{5} + x^{3} + 8 x^{2} + 8 = 0

x^{3} - 2 x^{2} + 16 = 0

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