5 x^{3} + 11 x^{2} + 7 x + 1 = 0

x = - 1, x = - \frac{1}{5}

Solution steps

5 x^{3} + 11 x^{2} + 7 x + 1 = 0

Factor

5 x^{3} + 11 x^{2} + 7 x + 1 : (x + 1)^{2} (5 x + 1)

(x + 1)^{2} (5 x + 1) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x + 1 = 0 or 5 x + 1 = 0

Solve

x + 1 = 0 : x = - 1

Solve

5 x + 1 = 0 : x = - \frac{1}{5}

The solutions are

x = - 1, x = - \frac{1}{5}

4 x^{3} - 24 x + 1 = 0

x (x - 1)^{2} = 1

x^{8} + 8 x^{4} + 16 = 0

x^{2015} = x^{2016}

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