If x= 6 is the only x-intercept of the graph of a quadratic equation then Discriminant is 0
Given :
x= 6 is the only x-intercept of the graph of a quadratic equation
for any quadratic equation , we will get two x intercepts .
x=6 is the only x intercepts . From this we can say that the other x intercept is also 6
Two x intercepts are same that is x=6
Two x intercepts are real and equal . when the x values are real and equal we can says that discriminant is 0
When discriminant is positive , then there will be 2 real and unequal x intercepts
When discriminant is negative , then there will be 2 imaginary x intercepts
If x= 6 is the only x-intercept then Discriminant is 0
