factor

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

x = i, x = - i, x = - 2, x = 2

Solution steps

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

Factor

x^{4} - 3 x^{2} - 4 : (x^{2} + 1) (x + 2) (x - 2)

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

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

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

Solve

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

Solve

x + 2 = 0 : x = - 2

Solve

x - 2 = 0 : x = 2

The solutions are

x = i, x = - i, x = - 2, x = 2

(2 x + 4)^{2} - (x + 3)^{3} = 0

y, 4 x y^{4} - x^{3} = y^{2} + 5

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

- 12 x^{3} + 24 x^{2} - 12 x = 0

x^{12} = 5000
