B. Triangles ABD and CBD are similar by the SSS Similarity Postulate.
C. Triangles ABD and CBD are congruent by the SAS Congruence Postulate.
D. Triangles ABD and CBD are similar by the SAS Similarity Postulate.

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0

it would be 3 0ver 24 very unlikely.
