Since, a and 1/a are the zeroes of the polynomial given, therefore
a* 1/a = (k+7)/4. [ Product of zeroes= c/a]
Therefore, (k+7)/4=1
Ie,. k+7=4
So,. k= -3
a* 1/a = (k+7)/4. [ Product of zeroes= c/a]
Therefore, (k+7)/4=1
Ie,. k+7=4
So,. k= -3
lufjoy:
what is "c" stand for? constant?
a stands for the coffecient of X2
b stands for the coffecient of x( though we don't need that here)
b stands for the coffecient of x( though we don't need that here)
And c stands for the constant
