hi!
solve this one....
ques1) (x+1)(x-2)(x+3)(x-4) ............ (x-100) = a0 + a1x + a2x^2 + ......
find the value of a1 ???
a1 = sum of the terms associated with x
= 99 + (-2) 99 + 3 x 99 + . . . . .
= 99 [ 1 - 2 + 3 - 4 + . . . . . + 99 - 100]
= 99 x (-50)
= -4950
Hey!
Thanks for replying. but i m not able to understand. could u further elaborate ur answer.
thanks...
co-efficient of x is sum of product of 99 terms taken at a time
so...a1=100!(1-1/2+1/3-1/4+.....-1/100)=100!log2 base e
can ny 1 confirm the answr plz
