Question

State the number of complex roots and the possible number of real and imaginary roots for each equation. The find all roots? If possible.

Answer 1

x =2

x = -2

Explanation:

(x - 2)(x + 2)(x^2 + 4) = 0

(x - 2) = 0

x = 0 + 2

x = 2

(x + 2) = 0

x = - 2

x = - 2

(x^2 + 4) = 0

x^2 = 4

x =
`√(4)`

x = 2
