2 x^{3} - 3 x^{2} + 98 x + 50 = 0

x = - \frac{1}{2}, x = 1 + 7 i, x = 1 - 7 i

Solution steps

2 x^{3} - 3 x^{2} + 98 x + 50 = 0

Factor

2 x^{3} - 3 x^{2} + 98 x + 50 : (2 x + 1) (x^{2} - 2 x + 50)

(2 x + 1) (x^{2} - 2 x + 50) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

2 x + 1 = 0 or x^{2} - 2 x + 50 = 0

Solve

2 x + 1 = 0 : x = - \frac{1}{2}

Solve

x^{2} - 2 x + 50 = 0 : x = 1 + 7 i, x = 1 - 7 i

The solutions are

x = - \frac{1}{2}, x = 1 + 7 i, x = 1 - 7 i

x^{3} + 4 x^{2} + 4 x - 1 = 0

a, v = a^{3}

2 x^{3} - 16 x^{2} + 14 x = 0

y, x = y^{4} - 8 y^{2} + 3

3 x^{4} - 10 x^{2} - 8 = 0
