Answer: x means multiply so in this problem see if there is anything you can multiply.
Step-by-step explanation:
Answer:
1, 3, 4
Step-by-step explanation:
Since the y intercept is the only number without a varible you choose the ones that are the same
Answer:
![$\[x^2 + 22x + 121\]$](https://tex.z-dn.net/?f=%24%5C%5Bx%5E2%20%2B%2022x%20%2B%20121%5C%5D%24)
Step-by-step explanation:
Given
![$\[x^2 + 22x + \underline{~~~~}.\]$](https://tex.z-dn.net/?f=%24%5C%5Bx%5E2%20%2B%2022x%20%2B%20%5Cunderline%7B~~~~%7D.%5C%5D%24)
Required
Fill in the gap
Represent the blank with k
![$\[x^2 + 22x + k\]$](https://tex.z-dn.net/?f=%24%5C%5Bx%5E2%20%2B%2022x%20%2B%20k%5C%5D%24)
Solving for k...
To do this, we start by getting the coefficient of x
Coefficient of x = 22
<em />
Divide the coefficient by 2
![Result = 22/2](https://tex.z-dn.net/?f=Result%20%3D%2022%2F2)
![Result = 11](https://tex.z-dn.net/?f=Result%20%3D%2011)
Take the square of this result, to give k
![k= 11^2](https://tex.z-dn.net/?f=k%3D%2011%5E2)
![k= 121](https://tex.z-dn.net/?f=k%3D%20121)
Substitute 121 for k
![$\[x^2 + 22x + 121\]$](https://tex.z-dn.net/?f=%24%5C%5Bx%5E2%20%2B%2022x%20%2B%20121%5C%5D%24)
The expression can be factorized as follows;
![x^2 + 11x + 11x + 121](https://tex.z-dn.net/?f=x%5E2%20%2B%2011x%20%2B%2011x%20%2B%20121)
![x(x + 11)+11(x+11)](https://tex.z-dn.net/?f=x%28x%20%2B%2011%29%2B11%28x%2B11%29)
![(x+11)(x+11)](https://tex.z-dn.net/?f=%28x%2B11%29%28x%2B11%29)
![(x+11)^2](https://tex.z-dn.net/?f=%28x%2B11%29%5E2)
<em>Hence, the quadratic expression is </em>

C"(4, -3)
D"(2, -3)
Step-by-step explanation:
When you are graphing coordinates make sure you have graph paper. When you plot the coordinates you reflect it over the x axis. The slide down 2 units down.
