## Algebra 1

A) $\sqrt 13 - 2$ and $\sqrt 13 + 2$ B) $\sqrt 6 + 3$ and $\sqrt 6 + 3$ C) $\sqrt 5 - \sqrt 10$ and $\sqrt 5 + \sqrt 10$
Conjugates are the sum and difference of the same two terms A) $\sqrt 13 - 2$ has the conjugate of $\sqrt 13 + 2$ because the -2 changes to +2 in the conjugate B) $\sqrt 6 + 3$ has the conjugate of $\sqrt 6 + 3$ because the +3 changes to -3 in the conjugate C) $\sqrt 5 - \sqrt 10$ has the conjugate of $\sqrt 5 + \sqrt 10$ because the $-\sqrt 10$ changes to $+\sqrt 10$ in the conjugate
