(z^{2} + 7)^{2} = 0

z = 7 i, z = - 7 i

Solution steps

(z^{2} + 7)^{2} = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

Solve

z^{2} + 7 = 0 : z = 7 i, z = - 7 i

The solutions are

z = 7 i, z = - 7 i

15 x^{3} + 6 x^{2} - 10 x - 4 = 0

x^{3} - 11 x + 150 = 0

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

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

- 4 = r^{20} - 5
