1)Write a quadratic equation with integer coefficients that has -4+7i(Radical 3) and -4-7i(Radical 3) as its roots.

2) Solve your answer to part 1 using the quadratic formula verifying your answer

  • Math -

    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.
