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
