Answer:
two solutions
Step-by-step explanation:
If you have a discriminant value greater than zero (not zero and not negative), you're gonna have two solutions. For zero discriminant, one solution. For negative discriminant, no solutions at all.
Make sure you remember this. It will save you from solving a quadratic equation which has no solutions.

Answer:
3.7 < √14 < 3.8
Step-by-step explanation:
First approximation
9 < 14 < 16, so
3 < √14 < 4
Second approximation
14 is closer to 16 than to 9.
Is √14 between 3.7 and 3.8? If so, then
3.7² < 14 < 3.8²
13.69 < 14 < 14.44. TRUE
The inequality is 3.7 < √14 < 3.8.
