17)
x² + 8 = -8
x² = -8 - 8
x² = 16
x = ±√-16
x = ±√16i
x = <span>±4i
</span>
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 = <span>±</span>√3i
hope this helps, God bless!
Answer:
= 29/12 − -13/6
<span>= ((29 × 6) − (-13 × 12)) / (12 × 6) </span>
= (174 - -156) / 72
= 330/72
= 55/12
<span>= 4 7/12</span>
