Answer:
x₁ = i√5
x₂ = -i√5
Explanation:
Let's solve the equation using square roots.
4X^2 + 20=0
x² + 5 = 0 (Dividing by 4 at both sides of the equation)
x² = -5 (Subtracting 5 at both sides of the equation)
√x² = √-5 (Square root to both sides of the equation, √-1 = i)
x = +/- i√5 ( (Roots of the solution)
x₁ = i√5
x₂ = -i√5
