Solving Polynomials with Imaginary

Imagine a scenario where Aria is solving a polynomial equation with real coefficients in her math class. She finds that one solution of the equation is in the form (a - bi), where (b ≠ 0). Which of the following expressions must also be a solution according to the complex conjugate root theorem?

• (a + bi)

• (-a + bi)

• (-b + ai)

• (b - ai)
