Answer:
Zeroes: ± 6
Step-by-step explanation:
The given polynomial is: .
To find the zeroes of the polynomial we equate it to zero.
⇒
⇒
⇒ x = -6 and x = +6. They are the zeroes of the polynomial.
Since is a quadratic equation it will have two roots. Therefore, the roots are x = -6, -6.
Multiplicity of a root is the number of times the root appears as the solution for the equation.
This makes x = -6 as root with multiplicity two.
Similarly, will have three roots.
∴ x = +6, +6 , +6
x = +6 is a root with multiplicity three.
