Application +4 | -1
The equation ax2+2hxy+ay2=0a x^2+2 h x y+a y^2=0 represent a pair of coincident lines through the origin if
View answer and explanation
Correct option: D
h2=a2h^2=a^2
Option D (h2=a2h^2=a^2) is correct because for coincident lines, the condition is that the discriminant of the quadratic equation must be zero, leading to h2=a2h^2 = a^2.
