A) all values of p
B) all except one value of p
C) all except two values of p
D) exactly one value of p
Correct Answer: B
Solution :
Radical axis is \[x+5y+{{p}^{2}}+2p5=0\] Equation of circle is \[{{x}^{2}}+{{y}^{2}}+3x+7y+2p5+\lambda [x+5y+{{p}^{2}}+2p\] \[-5]=0\] ?. (i) (i) passes through (1, 1) \[\Rightarrow \]\[\lambda =\frac{-(2p+7)}{{{(p+1)}^{2}}}\] \[(p\ne -1)\]You need to login to perform this action.
