If | array ccc x^2-3 x & x-1 & x+3 x+1 & -2 x & x-4 x-3 & x+4 & 3 x array |=a x^4+b x^3+c x^2+d x+e , then what is the value of e ?
Options
- A-1
- B0
- C1
- D2
Correct answer
B. 0
Step-by-step solution
If we put x=0 | array ccr 0 & -1 & 3 1 & 0 & -4 -3 & 4 & 0 array |=0+0+0+0+ e it is skew-symmetric of order 3 3 So, e =0
