Solution for z^2-(3+i)z+a+2i=0 equation:


Simplifying
z2 + -1(3 + i) * z + a + 2i = 0

Reorder the terms for easier multiplication:
z2 + -1z(3 + i) + a + 2i = 0
z2 + (3 * -1z + i * -1z) + a + 2i = 0

Reorder the terms:
z2 + (-1iz + -3z) + a + 2i = 0
z2 + (-1iz + -3z) + a + 2i = 0

Reorder the terms:
a + 2i + -1iz + -3z + z2 = 0

Solving
a + 2i + -1iz + -3z + z2 = 0

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-2i' to each side of the equation.
a + 2i + -1iz + -3z + -2i + z2 = 0 + -2i

Reorder the terms:
a + 2i + -2i + -1iz + -3z + z2 = 0 + -2i

Combine like terms: 2i + -2i = 0
a + 0 + -1iz + -3z + z2 = 0 + -2i
a + -1iz + -3z + z2 = 0 + -2i
Remove the zero:
a + -1iz + -3z + z2 = -2i

Add 'iz' to each side of the equation.
a + -1iz + -3z + iz + z2 = -2i + iz

Reorder the terms:
a + -1iz + iz + -3z + z2 = -2i + iz

Combine like terms: -1iz + iz = 0
a + 0 + -3z + z2 = -2i + iz
a + -3z + z2 = -2i + iz

Add '3z' to each side of the equation.
a + -3z + 3z + z2 = -2i + iz + 3z

Combine like terms: -3z + 3z = 0
a + 0 + z2 = -2i + iz + 3z
a + z2 = -2i + iz + 3z

Add '-1z2' to each side of the equation.
a + z2 + -1z2 = -2i + iz + 3z + -1z2

Combine like terms: z2 + -1z2 = 0
a + 0 = -2i + iz + 3z + -1z2
a = -2i + iz + 3z + -1z2

Simplifying
a = -2i + iz + 3z + -1z2
