想請問（2、3）要怎麼解？ ［學測數學複習：多項式］

99117=9
[EX] f(x) P & cx (X-1) 2 P₁ (X)=2x+1 F =Qxq+R
(X-2) 2 F₂ ( x ) = x + 3
(²) f ( x ) | / | | | (x-1) (X-2) | Rs (x) = ? pz (x) = x + |
(2)f(x)除以(x-1)(x-2)之4(x)=?
(3) f(x) P = (X (x-1) (x-2) |_ P5 (X) = 1
(1) f (x)) = q(x) (x-1) (X-1) + (ax+b) = 29th
1) f11) = a + b = 13² = f(2) = 29 +6 = 5 >9=2, b =
