Answer:

D

Step-by-step explanation:

[tex]y=x^2-11x+7[/tex]

we need to calculate [tex]\Delta = \sqrt{b^2-4ac}[/tex]

and if [tex]\Delta[/tex] is positive we have 2 distinct roots

if [tex]\Delta[/tex] is 0 then we have two identical roots.

If [tex]\Delta[/tex] < 0 then we  have two complex solutions.

in this case, [tex]\Delta = \sqrt{11^2-4*7} = \sqrt{121-28}>0[/tex]

the answer is D
