x^{5} - 2.2 x^{4} - 6.61 x^{3} + 8.602 x^{2} = 0

x = 0, x = \frac{17}{5}, x = \frac{11}{10}, x = - \frac{23}{10}

Decimal Notation

x = 0, x = 3.4, x = 1.1, x = - 2.3

Solution steps

x^{5} - 2.2 x^{4} - 6.61 x^{3} + 8.602 x^{2} = 0

Factor

x^{5} - 2.2 x^{4} - 6.61 x^{3} + 8.602 x^{2} : x^{2} (x^{3} - 2.2 x^{2} - 6.61 x + 8.602)

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

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

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

Solve

x^{3} - 2.2 x^{2} - 6.61 x + 8.602 = 0 : x = \frac{17}{5}, x = \frac{11}{10}, x = - \frac{23}{10}

The solutions are

x = 0, x = \frac{17}{5}, x = \frac{11}{10}, x = - \frac{23}{10}

p^{4} - 81 = 0

- x^{3} + x^{2} + 17 x + 15 = 0

6 x^{3} + 37 x^{2} - 34 x + 7 = 0

x^{3} = x^{2} - 7 x + 7

n^{3} + 2 n^{2} - 9 n - 18 = 0
