Answer: 2x^2+2x-4-\frac{4}{x+1}

Not a factor because there is a remainder.

Step-by-step explanation:

Let's use synthetic division to solve this..

-1  ║ 2 | 4 | -2 | -8

   ║    | -2| -2 |  4

   ║ 2 | 2|  -4 |  -4

2x^2+2x-4-\frac{4}{x+1}

PS: if anyone knows a better way to do a synthetic division chart please let me know.

Write the quadratic function in vertex form.<br><br> y = x2 - 2x + 5
Jlenok [28]
Vertex form formula: y = a(x-h)^2 +k, with vertex (h,k)
There are multiple ways to find the vertex. One way is to find the roots and then find the x value exactly in between them, because this parabola is symmetrical. 

0 = (x - 3)(x + 2), so x = 3 and -2. The point directly in the middle is x = 1/2 = h 

To find the y value of the vertex, plug in 1/2 to the equation.

(1/2)^2 - 2(1/2) + 5 = 4.25 = k

y = (x - 0.5)^2 + 4.25

Answer:

<h2>0.00390625 / 4^{-4} </h2>

Step-by-step explanation:

so you are saying do:

4^{2} /4^{6} which is 16 /4096

16/4096=0.00390625

<u>another way you can do this is</u>

4^{2} /4^{6}

just subtract the powers

2-6=-4
