Explanation Given: The rational expression 20 − x 2 ( x + 2 ) ( x − 2 ) 2 = A x + 2 + B x − 2 + C ( x − 2 ) 2 . Calculation: Considering the rational expression 20 − x 2 ( x + 2 ) ( x − 2 ) 2 = A x + 2 + B x − 2 + C ( x − 2 ) 2 Multiplying right side of the equation so that all the denominators are same. = A ( x − 2 ) 2 ( x − 2 ) 2 ( x + 2 ) + B ( x + 2 ) ( x − 2 ) ( x + 2 ) ( x − 2 ) 2 + C ( x + 2 ) ( x − 2 ) 2 ( x + 2 ) Now equating both sides of the expression 20 − x 2 = A ( x − 2 ) 2 + B ( x + 2 ) ( x − 2 ) + C ( x + 2 ) Let x = − 2 , 0 , 2 , we get the system of equation as, When, x = − 2 , 20 − ( − 2 ) 2 = A ( − 2 − 2 ) 2 + B ( − 2 + 2 ) ( − 2 − 2 ) + C ( − 2 + 2 ) 16 = 16 A When, x = 0 20 − ( 0 ) 2 = A ( 0 − 2 ) 2 + B ( 0 + 2 ) ( 0 − 2 ) + C ( 0 + 2 ) 20 = 4 A − 4 B + 2 C When, x = 4 20 − ( 2 ) 2 = A ( 2 − 2 ) 2 + B ( 2
