Answer:
Step-by-step explanation:
You need to know:
Vertex form =
The vertex is at
(h, k)
<u>Need to know about perfect squares </u>
<u>Need to know how to complete the square.</u>
-----------------------------------------------------------------------------------------
<u>To convert you need to complete the square on the equation.</u>
Complete the Square
Divide -2 by 2 and then square it.
Add the one to the parentheses and subtract the one from the 5
Square
Now we have
<u>Next add</u> -5 - 1 = -6
Our quadratic is in vertex form now.
Vertex form =
our equation =
Vertex = (1, -6)

Note: Consider we need to find the vertices of the triangle A'B'C'
Given:
Triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C'.
Triangle A,B,C with vertices at A(-3, 6), B(2, 9), and C(1, 1).
To find:
The vertices of the triangle A'B'C'.
Solution:
If triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C', then
Using this rule, we get
Therefore, the vertices of A'B'C' are A'(6,3), B'(9,-2) and C'(1,-1).
