Riel completed the work below to show that a triangle with side lengths of 9, 15, and 12 does not form a right triangle. is ariel’s answer correct? no, ariel should have added 122 and 152 and compared that to 92. no, ariel should have subtracted 122 from 92 and compared that to152. no, ariel should have added 92 and 122 and compared that to 152. yes, ariel’s work is correct.

step-by-step explanation:

step-by-step explanation:

the true ones are a b and d

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
