Question

Solve each equation and leave the answer in terms of “i”

17.) x^2+8=-8
18.) x^2+5=-3
19.) x^2+3=0

Answer 1

17)
x² + 8 = -8
x² = -8 - 8
x² = 16
x = ±√-16
x = ±√16i
x = ±4i

18)
x² + 5 = -3
x² = -3 - 5
x² = -8
x = ±√-8
x = ±√8i
x = ±2√2i

19)
x² + 3 = 0
x² = -3
x = ±√-3
x = ±√3i

hope this helps, God bless!
