Mai poured `2.6` liters of water into a partially-filled pitcher. The pitcher now contains `10.4` liters. Mai wants to know how
many liters of water were originally in the pitcher. Three of Mai’s friends drew a diagram (shown) to represent the problem.
You said the solution to your equation `2.6+10.4=` was `13`.
Explain what the solution to the equation means within the context of the problem.

Answer:
141, meaning that there will be two real solutions
Step-by-step explanation:
The discriminant of a quadratic is , which in this case is:
Since the discriminant is positive and not zero, there will be two real solutions to this equation. This is because when the discriminant is negative, and you take the square root of it, you get a negative number. If you take the square root of 0, you get 0, which means that there will only be one solution to the equation.
