Answer:

Step-by-step explanation:

The discriminant is

[tex]b^2-4ac[/tex]

Depending upon what this is equal to will dictate the number and type of zeros our quadratic has. For this, the discriminant is:

[tex](-84)^2-4(49)(36)[/tex] = 0

This means that the radicand is a perfect square. We will have 2 real, rational solutions.
