- x^{3} + 4 x^{2} + 25 x - 100 = 0

x = 4, x = - 5, x = 5

Solution steps

- x^{3} + 4 x^{2} + 25 x - 100 = 0

Factor

- x^{3} + 4 x^{2} + 25 x - 100 : - (x - 4) (x + 5) (x - 5)

- (x - 4) (x + 5) (x - 5) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x - 4 = 0 or x + 5 = 0 or x - 5 = 0

Solve

x - 4 = 0 : x = 4

Solve

x + 5 = 0 : x = - 5

Solve

x - 5 = 0 : x = 5

The solutions are

x = 4, x = - 5, x = 5

9 = x^{5} + x^{3} + x

3 x^{3} - 4 x^{2} - 48 x + 64 = 0

10000 = 1 x^{10}

5 x^{4} - 40 x = 0

555 = 5 x^{3}
