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:
She shaded area?
12 x 10 = 120
6 x 7 = 42
42 divided by 2 = 21
Now we subtract both areas:
120 - 21 = 99 of the shaded region.
Step 1) Divide 6 and 4 (the last 2 numbers) and bring everything else down
<em>6x^24x+2x+4</em>
Step 2) Place in parentheses
<em>(6x^24x)+(2x+4)</em>
Step 3) Figure out what you can take out of each parentheses.
**In the first one, you can take out 6x because both numbers have x and 6 is the largest number 6 and 24 can go into.**
**In the second one, you can only take out 2 because 2 is the largest number that goes into 2 and 4.**
Step 4) You will know you did it correctly when the parentheses match up
<em>6x(x+4) + 2(x+4)</em> <<< this is how it should look
Answer: <em>(6x+2)(x+4)</em>
