Thread: Alg2/trig help

1. One root of a quadratic equation is 3+2i. Determine the other root and write the equation that has these values as its roots.

2. Solve for x in simplest a+bi form: 4x-4 = - 17/x

Any help would be appreciated please show steps.

The complex conjugate will be the other root. Now you have both roots, expand them out the find the original equation.

multiplying your equation through by x will give you



now solve using the quadratic formula.
