Evaluate the Given Polynomial: -x%5E3+%2B+2x%5E2++%2B+3x+-5%3B+x+=+1%2F2+-+3i
Okay so it looks to me like a simple plug And play(X=#, so put the # in place of all the X's in the equ). So here is the solution and steps i came up with.
-x%5E3+%2B+2x%5E2++%2B+3x+-5
-%281%2F2+-+3i%29%5E3+%2B+2%281%2F2+-+3i%29%5E2+%2B+3%281%2F2+-+3i%29+-+5
13.375+-+24.75i+-+17.5+-+6i+%2B+1.5+-+9i+-+5
-7.625+-+39.75i
