求解2.3.5題
+2)+2/ B A=(2x+1)(3x-4)+5 =6x-5x+1 單元1 乘法公式與多項式 49 立即測驗 1.若多項式除以2x+1得商式為3x-4,餘式為5,則4=6X-5+1 2. 若3x²+11x+8除以ax+b得到商式x+2,餘式為-2,則a= 〖基測〗 b= 3. Q、R為多項式,依除法原理 x 2 - 5x +6 x+2 R 2+ x+2 則Q= 4. 設B為多項式,若 x²+4x+ 5 2 x+1+ 9 B 則B=x+3 0 B 5. 以(x+1)*除(x+1)*-4x2-3x+7所得的餘式為 ,R= x+4X+5=(x+14()+2 x+4x+3=(x+1)(x+3 (D) 6. 多項式A除多項式B,所得之商與餘式各為Q、R,則下列何者正確? (A)A = A x R 3x B BQ+R(B) =Q+RCOB=AQ+R (1) 1/2= 2+128 (A)7. 若x*+2x+4 X - 1 B (x+3)+C,則C=? 7 1 (A) (B) 7 (C) x- 1 (D) 1. x 1 B 3x-1 8.二多項式A、B,已知B為3x-2,欲求A+B,但某生因誤將A+B看成A÷B,結果求出 之答案是9x²+6x+4,求A+B之正確答案。 27x3-8+3X-2 ( )÷(3x-2)=9x+6X+4 1)=BX-2)(9x+6x+4) = 27x-8 = 27X²+3X-10
