Final answer:
A polynomial with one root in the form a + √5 does not necessarily have a second root in the form a√√5.
Step-by-step explanation:
If a polynomial has one root in the form a + √5, it does not necessarily have a second root in the form of a√√5. The second root could have any form, depending on the polynomial equation. In general, if a polynomial has one root in the form a + √b, it will have a conjugate root in the form a - √b, where b is a positive number and a is any real number.
