For how many values of p, the circle x^2 + y^2 + 2x + 4y - p=0 and the coordinate axes have exactly three common points?
x2+y2+2x+4y−p=0Case(I)(0)2+(0)2+0+0p=0Case(II)g2−c=0f2−c>01−(−p)=0p=−14−(−p)>0p>−4Case(III)f2−c=04−(p)=0p=−4g2−c>01−(−p)>0p>−1∴ Total 2 values of p, the circle and the co-ordinate have 3 common point.
