Question

Which statement is true about this quadratic equation?

Answer 1

Answer:

i think B

Step-by-step explanation:

because is right

Answer 2

Answer:

D

Step-by-step explanation:

$y=x^2-11x+7$

we need to calculate $\Delta = \sqrt{b^2-4ac}$

and if $\Delta$ is positive we have 2 distinct roots

if $\Delta$ is 0 then we have two identical roots.

If $\Delta$ < 0 then we  have two complex solutions.

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

the answer is D
