15 x^{4} - 20 x^{3} = 0

x = 0, x = \frac{4}{3}

Solution steps

15 x^{4} - 20 x^{3} = 0

Factor

15 x^{4} - 20 x^{3} : 5 x^{3} (3 x - 4)

5 x^{3} (3 x - 4) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or 3 x - 4 = 0

Solve

3 x - 4 = 0 : x = \frac{4}{3}

The solutions are

x = 0, x = \frac{4}{3}

x^{3} - 11 x^{2} + 30 = 0

M = (x + 5) (x - 5) (x^{2} + 25) + 625

2 x^{4} = + 6 (0.6 - 4)

2 a^{3} - 2 a^{2} + 1 = 0

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