Which of the following is the discriminant of the polynomial x^+6x+8

4

Step-by-step explanation:

I would assume you meant the polynomial x^2+6x+8

The discriminant can be found with b^2-4ac

where the quadratic equation is in the form ax^2+bx+c

=6²-4*(1)(8)

=4

step-by-step :

i think the answer is b x = 1, y = 35/2
