Which question do you need
Completing the square is a method used to solve a quadratic equation by changing the shape of the equation so that the left side is a perfect square trinomial.
The following equation makes more sense to solve it complete squares:
x² + 20x = 52
We have then:
x² + 20x + (10) ^ 2 = 52 + 100
(x + 10) ² = 152
Answer:
The most sense to solve by completing the square is for:
B) x² + 20x = 52
Answer: $38,824
Step-by-step explanation:
Convert the mixed number 
as a decimal number.
Divide the numerator by the denominator and add it to the whole number 4. Then:
Then, knowing that 4.25 acres cost $165,000 , divide this amount by 4.25 acres to find the cost of each acre.
Therefore, you get that the cost of each acre rounded to nearest dollar is:
As written, the denominator in both fractions is x, so the only restriction on the domain is ... x ≠ 0.
_____
We suspect you intend ...
... f(x) = 2/(x-4) +1/(x+2)
which is undefined when x = 4 or x = -2.
The domain is all real numbers except -2 and 4.
A Prime Number can be divided evenly only by 1 or itself.
And it must be a whole number greater than 1.
