Answer:
A polynomial function that meet those conditions is x² + x - 2 = 0
Step-by-step explanation:
Hi there!
To solve this problem, let´s start writting a generic polynomial function in factored form. Since the function has two zeros, the factored form will have 2 terms:
(x+a)(x+b) = 0
For this equation to be 0, (x+a) or (x+b) have to be zero:
Then:
x + a = 0 ⇒ x = -a
In the same way:
x + b = 0 ⇒ x = -b
Then, the values "a" and "b" are equal to the zeros of the function but with the opposite sign.
In our case:
(x + a)(x + b) = 0
a = the zero of the function with opposite sign, that is, 2
b = -1
Then:
(x + 2)(x - 1) = 0
Apply distributive property:
x² - x + 2x - 2 = 0
x² + x - 2 = 0
Then, a polynomial function that meet those conditions is:
x² + x - 2 = 0
When you have an exponent that is negative, it means to take reciprocal of the fraction then take it the power.
Some examples:
5^-2 = 1/5^2 = 1/25
10^-3 = 1/10^-3 = 1/1000

To calculate the midpoint,here's the formula : ((x1+x2)/2 , (y1+y2)/2)
thus, we have:
((10+(-4))/2 , (6+8)/2)
=(6/2 , 14/2)
=(3,7)
The coordinate for the midpoint is (3,7)
hope it helps!
Answer:
honestly this is a very poorly worded question...
it can be interpreted in several different ways....
the cost of the house (for them to purchase it) was
$129,625 + $18,375 = $148,000
The total amount that they paid for the house (money spent)
was
$129,625 + $18,375 + $273,116 = $421,116
all being said I think that the $148,000 is the answer that the question
is trying for you to figure out
