Completing the Square

2. Solve the equation by completing the square. Show your work.

x^2 – 30x = –125

Step 1: Add to both sides of the equation. (2 points)

Add 225 both sides of the equation

x^2 – 30x + 225 = –125 + 225

x^2 - 30x + 225 = 100

Step 2: Factor the left side of the equation. Show your work. (2 points)

Hint: It is a perfect square trinomial.


x^2 - 30x + 225 = 100


Factor the left side of the equation:

(x - 15)^2 = 100

Step 3: Take the square root of both sides of the equation from Step 2. (1 point)

√(x - 15)^2 = √100


Step 4: Simplify the radical and solve for x. Show your work. (1 point)

x - 15 = + - 10


x - 15 = 10

x = 25


x - 15 = -10

x = 5


Solutions x = 25, 5

1) the 3 measures of central tendency is mean, median, and mode.

So when finding the average clutch size is by using mean.

Clutch sizes:

114, 103, 121, 118, 107, 103, 104
114+103+121+118+107+103+104
=770
= 770 ÷ 7 ( 7 ⇒ there are seven numbers in total)
= 110

∴ Therefore the average clutch size is 110.

2) Through that table of data, yes, I think that the clutch size influences the survival rates of the offspring because it seems that when the clutch size is big, it is more likely for offspring to survive and return. Yet when the clutch size are small, for example, site E and G, the amount of turtles who returned are 40 and 38. But in site A, C, and D, there are 45 turtles in site A that returned, 55 turtles in site C, and 53 turtles in site D.

3) Possibly is because their clutch sizes are the smallest which made them unnoticeable to predators and more likely to survive and returned.
