x^{3} - 15 x^{2} - 28 x = 0

x = 0, x = \frac{15 + 337}{2}, x = \frac{15 - 337}{2}

Decimal Notation

x = 0, x = 16.67877 \dots, x = - 1.67877 \dots

Solution steps

x^{3} - 15 x^{2} - 28 x = 0

Factor

x^{3} - 15 x^{2} - 28 x : x (x^{2} - 15 x - 28)

x (x^{2} - 15 x - 28) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x^{2} - 15 x - 28 = 0

Solve

x^{2} - 15 x - 28 = 0 : x = \frac{15 + 337}{2}, x = \frac{15 - 337}{2}

The solutions are

x = 0, x = \frac{15 + 337}{2}, x = \frac{15 - 337}{2}

x, f = k (x)^{2} m (x)^{3}

n, y = (2 n + 1)^{3}

p^{3} + 3 p^{2} + 2 p = 7980

4 x^{3} = 9 x

8 x^{3} + 12 x^{2} + 6 x + 1 = 0
