Answer:
Answer A in your list
Step-by-step explanation:
Simply replace x in the expression for f(x) with "x+h" and perform any squaring of binomials as needed:
If
, then:

which is the first answer in your list of possible options

first , set the function equal to zero

now we can use this expression to factor
![x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-b%5Cpm%5Csqrt%5B%5D%7Bb%5E2-4ac%7D%7D%7B2a%7D)
where a is 6, b is 1 and c -2
so, replacing
![\begin{gathered} \frac{-(1)\pm\sqrt[]{1^2-4(6)(-2)}}{2(6)} \\ \\ \frac{-1\pm\sqrt[]{1+48}}{12} \\ \\ \frac{-1\pm\sqrt[]{49}}{12} \\ \\ x=\frac{-1\pm7}{12} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cfrac%7B-%281%29%5Cpm%5Csqrt%5B%5D%7B1%5E2-4%286%29%28-2%29%7D%7D%7B2%286%29%7D%20%5C%5C%20%20%5C%5C%20%5Cfrac%7B-1%5Cpm%5Csqrt%5B%5D%7B1%2B48%7D%7D%7B12%7D%20%5C%5C%20%20%5C%5C%20%5Cfrac%7B-1%5Cpm%5Csqrt%5B%5D%7B49%7D%7D%7B12%7D%20%5C%5C%20%20%5C%5C%20x%3D%5Cfrac%7B-1%5Cpm7%7D%7B12%7D%20%5Cend%7Bgathered%7D)
x has two values


we have the two roots now we chang the sign and make the factor expression
Hello!
You solve this algebraically
4n - 9 = -9
Add 9 to both sides
4n = 0
Divide both sides by 4
n = 0
The answer is 0
Hope this helps!
2x + 2x + x = 180°
5x = 180°
x = 36° (C)
