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
Answer:
If these are ratios, then
2:7 = 6:21
Answer:
I think your question is not complete..
can you write the question in a way which will determine in what way you want your answer..
i mean from what to find x..
Area is given as 285cm
what is 15 cm for?
from here where is x given to find?
Answer:
-5
Step-by-step explanation:
we distribute the 3 and 2 on both sides to get:
3x+3=2x-2
we can subtract 3 on both sides to get
3x=2x-5
Now we subtract 2x on both sides to get
x=-5
Hope this helps :)
Answer:
Step-by-step explanation:
These are "like terms," as both terms contain √5. We add the coefficients together but leave the radical term √5 as is:
√5
+ 6√5
-----------
7√5
