Answer:
substitute that value for x in the polynomial and see if it evaluates to zero
Step-by-step explanation:
A "zero" of a polynomial is a value of the polynomial's variable that make the expression become zero when it is evaluated. As an almost trivial example, consider the polynomial x-3. The value x = 3 is a zero because substituting that value for x makes the expression evaluate as zero.
3 -3 = 0
___
Evaluating polynomials can be done different ways. Straight substitution for the variable is one way. Using synthetic division by x-a (where "a" is the value of interest) is another way. This latter method is completely equivalent to rewriting the polynomial to Horner form for evaluation.

Answer:
15 cm.
Step-by-step explanation:
It is given that,
Central angle
Arc length = 33 cm
Formula for arc length :
where, s is arc length, r is radius and is central angle in radian.
Substitute s=33 and in the above formula.
Multiply both sides by 10.
Divide both sides by .
Put
Therefore, the radius of the circle is 15 cm.
