Question

Solve the Quadratic Equation.

Answer 1

Answer:

x = ± 2i

Step-by-step explanation:

The equation has no real roots, gut has complex roots

Given

x² = - 4 ( take the square root of both sides )

x = ± $\sqrt{-4}$

  = ± $\sqrt{4(-1)}$

[ Note that $\sqrt{-1}$ = i ]

  = ± $\sqrt{4}$ × $\sqrt{-1}$ = ± 2i
