ANSWER
A. -3, -2, 2, and 3
EXPLANATION
The given polynomial function is,

To find the real roots, we equate the function to zero to obtain;

We can solve this equation as a quadratic equation in

Thus we rewrite the equation as,

We split the middle term to get,

We factor to get,

We factor to get,

Either

or




The correct answer is A
The value of a is 
Step-by-step explanation:
<u>1. Determine the other solution of x</u>
If one value is 5 +
then the other value is 5 - 
<u>2. Use reverse technique to find the equation</u>
(5 +
) (5 -
) = 0
25 -
+
-
= 0
-
+ 25 = 0
<u>3. The equation is</u> -
+ 25 = 0
<u>4. Find the value of a</u>
a is the number with the variable
therefore it is -
