Solving the Complex Equation: (z+5i)(4+2i)-(z+2)(4+2i)=24+2i
This article will guide you through the steps to solve the complex equation: (z+5i)(4+2i)-(z+2)(4+2i)=24+2i.
Let's break it down:
Simplifying the Equation
-
Distribute: Expand the products on both sides of the equation:
- (z+5i)(4+2i) = 4z + 2zi + 20i - 10
- (z+2)(4+2i) = 4z + 2zi + 8 + 4i
-
Substitute: Substitute the expanded products back into the original equation:
- (4z + 2zi + 20i - 10) - (4z + 2zi + 8 + 4i) = 24 + 2i
-
Simplify: Combine like terms:
- 16i - 18 = 24 + 2i
Solving for z
-
Isolate i terms: Subtract 2i from both sides and add 18 to both sides:
- 14i = 42
-
Solve for i: Divide both sides by 14:
- i = 3
-
Substitute i back: Since we know i = 3, there is no 'z' term in the equation, meaning there is no solution for 'z'.
Conclusion:
The equation (z+5i)(4+2i)-(z+2)(4+2i)=24+2i has no solution for 'z'. This is because the equation simplifies to an equation with only 'i' terms, and there is no 'z' term to solve for.
