Can you help me with this one please.

With which bit do you need the help? Finding the conjugate is a simple matter of applying the definition they gave you. Finding the product is just a matter of multiplying the two expressions, just like you did when you multiplied binomials.

Please show your work and reasoning. Thank you!
