roots

x^{3} - 3 x^{2} - 13 x + 15

x = 1, x = - 3, x = 5

Solution steps

x^{3} - 3 x^{2} - 13 x + 15

The roots are the intercepts with the x-axis

(y = 0)

x^{3} - 3 x^{2} - 13 x + 15 = 0

Factor

x^{3} - 3 x^{2} - 13 x + 15 : (x - 1) (x + 3) (x - 5)

(x - 1) (x + 3) (x - 5) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x - 1 = 0 or x + 3 = 0 or x - 5 = 0

Solve

x - 1 = 0 : x = 1

Solve

x + 3 = 0 : x = - 3

Solve

x - 5 = 0 : x = 5

The solutions are

x = 1, x = - 3, x = 5

x = x^{3} - x^{2} - x

x^{3} - 5 x^{2} + 4 x - 20

500 = 0.02 \frac{t ^{4}}{12}

s^{4} + 60 s^{3} + 1400 s^{2} + 2000 s - 130000 = 0

x^{4} - 12 x^{3} + 77 x^{2} - 260 x + 500 = 0
