x^{3} - 2.2 x^{2} - 6.61 x + 8.602 = 0

x = \frac{17}{5}, x = \frac{11}{10}, x = - \frac{23}{10}

Decimal Notation

x = 3.4, x = 1.1, x = - 2.3

Solution steps

x^{3} - 2.2 x^{2} - 6.61 x + 8.602 = 0

Multiply both sides by

1000

1000 x^{3} - 2200 x^{2} - 6610 x + 8602 = 0

Factor

1000 x^{3} - 2200 x^{2} - 6610 x + 8602 : 2 (5 x - 17) (10 x - 11) (10 x + 23)

2 (5 x - 17) (10 x - 11) (10 x + 23) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

5 x - 17 = 0 or 10 x - 11 = 0 or 10 x + 23 = 0

Solve

5 x - 17 = 0 : x = \frac{17}{5}

Solve

10 x - 11 = 0 : x = \frac{11}{10}

Solve

10 x + 23 = 0 : x = - \frac{23}{10}

The solutions are

x = \frac{17}{5}, x = \frac{11}{10}, x = - \frac{23}{10}

9 m^{5} - 27 m^{3} = 0

x^{4} - 4 x^{3} - 6 x^{2} + 4 x + 5 = 0

3 x^{4} + 17 x^{2} - 6 = 0

3 x^{3} - 10 x^{2} - 9 x + 4 = 0

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