1)Write a quadratic equation with integer coefficients that has 4+7i(Radical 3) and 47i(Radical 3) as its roots.
2) Solve your answer to part 1 using the quadratic formula verifying your answer

drwls,
1) [x  (root1)][x  (root2)] = 0
Substitute in the two roots and multiply it out.
2) You should be able to do your own verification using the quadratic formula,
x = [b +/ sqrt(b^2/4ac)]/(2a)
a,b and c are the coefficients in your quadratic equation from part 1.
