Question

Create your own binomial expression with a radical in the second term.

Part 1: Identify its conjugate and explain, in complete sentences, why it is the conjugate. (1 point)

Part 2: Multiply your original binomial expression and its conjugate. What happened to the radicals and why? (1 point)

Answer 1

still nobody gave you answer?

Answer 2

\[(a+\sqrt{b})\]
conjugate:
\[(a-\sqrt{b})\]
multiply:
\[(a-\sqrt{b})(a+\sqrt{b})= a ^{2} -a \sqrt{b} + a \sqrt{b} -\sqrt{b}^{2}= a ^{2} -b\]
