Answer:
Step-by-step explanation:
+ 3 = -z
= -z - 3
Square both sides , we have
2z =
2z = + 6z + 9
re arranging the equation , we have
+ 6z - 2z + 9 = 0
+ 4z + 9 = 0
This will give a complex roots , solving by quadratic formula
z = -2 + i , -2 - i
Answer:
<em>If you mean √2z + 3 = -z, the answer is ∅</em>
If you mean √2 z + 3 = -z
√2 z + 3 = -z
√2 z = -z - 3
√2 z + z = - 3
z(√2 + 1) = -3
z = -3 / (√2 + 1)
z = -3 (√2 - 1)
