Answer:
I think is is a bit b
Step-by-step explanation:
a or b
Use the ! tool to find the # of combinations.
8!/5! = 40,320/120 = 336
f(x)=x^2+12x+26
Vertex form of f(x) = a(x-h)^2 +k
We change f(x) into vertex form using completing the square method

We take half of square of middle term
middle term is 12
Half of square of 12 is
then 6^2 = 36
Add and subtract 36 to complete the square


The vertex form
