Question

$irrational \\ conjugate \\of \sqrt{7} + \sqrt{2}$

Answer 1

Step-by-step explanation:

To find an irrational conjugate we simply change addition to subtraction or vice versa. The irrational conjugates theorem states that if the irrational number a + √b is an irrational root of a polynomial, then its irrational conjugate a - √b is also an irrational root of that polynomial.
