Question

If x= 6 is the only x-intercept of the graph of a quadratic equation, which statement best describes the discriminant of the

Answer 1

Answer:

The discriminant is 0.

Step-by-step explanation:

we know that

In a quadratic equation of the form $ax^{2} +bx+c=0$

The discriminant is equal to

$D=(b^{2}-4ac)$

If D=0 -----> The equation has only one real solution

If D>0 ----> The equation has two real solutions

If D<0 ----> The equation has complex solutions

In this problem

If the equation has only one intercept (x=6)

then

The equation has only one real solution

therefore

The discriminant is 0.
