Answer:
The irrational conjugate theorem states that if a polynomial equation has a root (a + √b), then we can say that the conjugate of (a + √b), i.e. (a - √b) will also be another root of the polynomial.
Step-by-step explanation:
The irrational conjugate theorem states that if a polynomial equation has a root (a + √b), then we can say that the conjugate of (a + √b), i.e. (a - √b) will also be another root of the polynomial.
For example, if we consider a quadratic equation x² + 6x + 1 = 0, then two of its roots are - 3 + √8 and - 3 - √8 and they are conjugate of each other. (Answer)

Answer:
3 is yes, the rest is no
Step-by-step explanation:
for y = -6x - 9
(1) if x = 7, y = -51 => No
(2) if x = 3, y = -27 => No
(3) if x = -8, y = 39 => Yes
(4) if x = -5, y = 21 => No
