## Algebra: A Combined Approach (4th Edition)

Find the coefficients $a$ and $b$ of the complex number $a+bi$. The conjugate of $a+bi$ is $a-bi$.
To find the conjugate of a complex number, simply change the sign of the imaginary part of the number. For example, the conjugate of $(5 + 4i)$ is $(5 - 4i)$.
