Moving all terms of the quadratic to one side, we have
.
A quadratic has one real solution when the discriminant is equal to 0. In a quadratic , the discriminant is
.
(The discriminant is more commonly known as , but I changed the variable since we already have a
in the quadratic given.)
In the quadratic above, we have ,
, and
. Plugging this into the formula for the discriminant, we have
.
Using the distributive property to expand and simplifying, the expression becomes
Setting the discriminant equal to 0 gives
.
We can then solve the equation as usual: first, divide by 2 on both sides:
.
Squaring both sides gives
,
and subtracting 5 from both sides, we have

Answer:
The area of the living room and hallway together = 437ft²
Question:
The complete question related to the one above found at 'Geometry in class' is stated below:
Abbey is getting new carpet in her living room and hallway.
The following diagram shows the two together.
If = 38 ft, b = 15 ft, c = 19 ft, and d = 19 ft, what is the area of the living room and hallway together?
Find attached the diagram of the question.
Step-by-step explanation:
To determine the area of the living room and hallway together, we would break the diagram into two rectangles.
Calculate the area of each and sum the two outcomes together.
Find attached the diagrams of the solution.
Given: a = 38 ft, b = 15 ft, c = 19 ft, and d = 19 ft,
Area of rectangle = length × breadth
Area of rectangle 1 = a × (d-b)
= 38 × (19-15) = 38× 4
Area of rectangle 1 = 152ft²
Area of rectangle 2 = c × b
= 19 × 15 = 285
Area of rectangle 2 = 285ft²
The area of the living room and hallway together = Area of rectangle 1 + Area of rectangle 2
= 152ft² + 285ft²
The area of the living room and hallway together = 437ft²
