given
16x² + 4 = 0 ( subtract 4 from both sides )
16x² = - 4 ( divide both sides by 16 )
x² =
= -
[ take the square root of both sides ]
x = ±
= ±

Answer:
x = ±1/2 i
Step-by-step explanation:
16x^2 +4 = 0
Subtract 4 from each side
16x^2 +4-4 = 0-4
16x^2 = -4
Divide by 16
16x^2/16 = -4/16
x^2 = -1/4
Take the square root of each side
sqrt(x^2) = sqrt(-1/4)
sqrt(ab) sqrt(a) sqrt(b)
x = ±sqrt(1/4) sqrt(-1)
x = ±1/2 i
