Given:
The quadratic equation is
To find:
The vertex of the given quadratic equation.
Solution:
If a quadratic function is 
, then
We have,
It can be written as
...(i)
Here, 
.
Putting 
in (i), we get
On further simplification, we get
So, the vertex of the given quadratic equation is 
.
Therefore, the correct option is A.
I factor it because you can't simplify
2x-8=2(x-4)
X^2+5x+4=(x+1)(x+4)
X^2-16=(x-4)(x+4)
X^2+8x+16=(x+4)(x+4)
Answer:
Counting by 2's 6
Counting by 5,2 but the you'd have to round
Answer:
Greatest to least is 0.836 , 0.683, 0.386 , 0.3.
Step-by-step explanation:
Given : 0.386; 0.3; 0.683; 0.836.
To find : which Is greatest to least.
Solution :" We have given 0.386; 0.3; 0.683; 0.836.
In 0.386
Tenth place is 3 and hundredth place is 8
In 0.3
Tenth place is 3 and hundredth place 0
In 0.683
Tenth place is 6 and hundredth place 8
In 0.836.
Tenth place is 8 and hundredth place 3.
So, Greatest number is 0.836 ,
Least number is 0.3.
Therefore, Greatest to least is 0.836 , 0.683, 0.386 , 0.3.
