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

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

Solution steps

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

Factor

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

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

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

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

Solve

x - 5 = 0 : x = 5

Solve

x + 1 = 0 : x = - 1

Solve

x - 1 = 0 : x = 1

The solutions are

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

r^{3} - r^{2} - r + 1

x^{4} - 729 x

7 x^{2} - 144 = - x^{4}

x^{3} - 13 x^{2} + 52 x - 60 = 0

- x^{3} + 14 x^{2} - 59 x + 70 = 0
