Question

If x6 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 equal to zero

Step-by-step explanation:

If x=6 is the only x-intercept of the graph of a quadratic equation, the it means the quadratic equation has a repeated root.

When a quadratic equation has a repeated root, it means its discriminant is zero.

This means that

${b}^{2} - 4ac = 0$
