Heres the Question :

3) Suppose we begin with the quadratic equation *We know the roots of the equation are given by the quadratic formula, * *Now let a, b, and c be all positive single digit integers (that is, from 1 to 9). For example, one such quadratic equation can be (a=3, b=4, c=1)* *Of all the possible quadratic equations of this type, if one equation is randomly picked, what is the probability that the roots of the equation will be rational?*
Thank you in advance for all your help!

hopefully someone can help me with this question !
