So, students should be able to solve equations such as:

Find the conjugate of a complex number and use conjugates to find moduli and quotients of complex numbers. A conjugate is a binomial expression (representing the sum or difference of two terms) formed by negating the second term of a binomial; for example, the conjugate of a + b is a – b.

When an imaginary number is involved, you have a complex conjugate; for example, in the expression m = a + bi the complex conjugate represented is . A sample problem may provide a given and ask you to use the conjugate to find the modulus and quotient; for example, given that y = 3 – 7i and z = 5 + 2i, find the modulus of y and the quotient of z and y:

To find the modulus of y using its complex conjugate, students may solve an equation like the following:
