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
Answer:
x=10
Step-by-step explanation:
6(x+2)=8(x-1)
x=10
Answer:
To solve for n you need to get it by itself
First you want to distribute your 2 through the (3n+14)
-2n+6n+28=-20 (2*3n+2*14= 6n+28)
Now you want to combine any like terms if possible
4n+28=-20 (-2n+6n=4n, both like terms)
Then you want to subtract -28 from both sides
4n=-48 (28-28=0, -20-28=-48)
Lastly you want to divide both sides by 4
n=-12 (4n/4=n, -48/4= -12)
Y = -1/2x - 1
Tell me if you need explanation
The X which is the first number in each () in called the input
There is only one input for every number
Meaning all the first numbers mystery br DIFFERENT
