What the question?
Or picture
I got.......6x^3 + 5x^2 - 3x - 2................not sure though
Answer:
y = (x-3)^2 -16
Step-by-step explanation:
y = x^2 -6x-7
We need to complete the square
b= -6
b/2 = -6/2 = -3
(b/2) ^2 = (-3)^2 =9
Add 9 then subtract 9 to balance the equation
y = x^2 -6x +9 -9 -7
y = (x^2 -6x+9) -16
The terms in parentheses is (x-b/2)^2
y = (x-3)^2 -16
This is in vertex form
The vertex is (3,-16)
Answer:
3a/6b
Step-by-step explanation:
12a^2/4a
= 12/4 * a^2/a
= 3a
18b^2/3b
= 18/3 * b^2/b
= 6b
Hence, the answer is 3a/6b.
Hope this helped!
