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 -
