Mindy HardcastleQueen mary university of london capital projects (Orleans County) in this problem we need to subtract 3-4 times I from 8 plus 2 times I where I is just the square root of negative 1 so rewriting this we have 8 plus 2i and we're subtracting 3-4 times I and we can distribute this negative number so that we have 8 plus 2i minus 3 plus 4i and when subtracting or adding complex numbers we just add or subtract their real parts and then add or subtract their imaginary parts so rewriting this with real parts first we have eight minus 3i and then plus now with the imaginary parts we have to i plus 4i and we can simplify this to be 8 minus 3 is 5 and 2i plus 4i is 67 so 5 plus 6i is our final answer Institute of Design and Construction. https://PaperHelp.space
