Answer:
Step-by-step explanation:
Simplifying
x2 + 3ix + 10 = 0
Reorder the terms:
10 + 3ix + x2 = 0
Solving
10 + 3ix + x2 = 0
Solving for variable 'i'.
Move all terms containing i to the left, all other terms to the right.
Add '-10' to each side of the equation.
10 + 3ix + -10 + x2 = 0 + -10
Reorder the terms:
10 + -10 + 3ix + x2 = 0 + -10
Combine like terms: 10 + -10 = 0
0 + 3ix + x2 = 0 + -10
3ix + x2 = 0 + -10
Combine like terms: 0 + -10 = -10
3ix + x2 = -10
Add '-1x2' to each side of the equation.
3ix + x2 + -1x2 = -10 + -1x2
Combine like terms: x2 + -1x2 = 0
3ix + 0 = -10 + -1x2
3ix = -10 + -1x2
Divide each side by '3x'.
i = -3.333333333x-1 + -0.3333333333x
Simplifying
i = -3.333333333x-1 + -0.3333333333x
