Options
- A29 4
- B23 4
- C5 4
- D4 5
Correct answer
C. 5 4
Step-by-step solution
4 x^2+5 (x-2)^4 = A x-2 + B (x-2)^2 + C (x-2)^3 + D (x-2)^4 A(x-2)^3+B(x-2)^2+C(x-2)+D=4 x^2+5 If x=2 D=21 Co-efficient of x^3, A=0 Constant term, 4 B-2 C+21=5 4 B-2 C=-16 Co-efficient of x^2, B=4 So, 16-2 C=-16 C=16 Now, A C + B C + D C = A+B+D C = 4+21 16 = 5 4 .
