Faith wants to test the effects of a weight-loss supplement. she asks several family members to participate in her experiment and after 3 weeks of using the supplement to see how their weight has changed. What is the bias?

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

true. i hope this ! go answer some of my newest

10 - 8 = -2

  8 - 6 = -2

etc, so -2 is the common difference
