Ответ:
2 real solutions since the discriminant is 4 and is greater than 0.
Furthermore, since 4 is a perfect square then the answers are also going to be rational.
You will have 2 real rational solutions.
Step-by-step explanation:
Compare the following to determine the values for :
.
.
Now we are going to compute:
So the discriminant is 4.
Here is the thing about discriminant (D) assuming are real:
If D=0, then you have one real solution.
If D<0, then you have no real solution.
If D>0, then you have two real solutions.
Our D (discriminant) is 4 and 4 is positive or >0, so we have two real solutions.
There is another thing we can tell about this particular discriminant.
Since it is a perfect square, then we know the answers will also be rational.
