Which of the following regression equations best fits the data shown below?

A. y=-3.69x^2 + 2.08x+8.07

B. y= -1.94x^2 + 0.62x + 9.62

C. y= -0.89x^2 + 3.24x+11.93

D. y=-2.37x^2 +1.02x + 10.91

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

believe it or not anna is correct good job anna give me a fist bump there u go gal

in my opinion , its hazel
