14^2+x^2+20^2=90
We move all terms to the left:
14^2+x^2+20^2-(90)=0
determiningTheFunctionDomain x^2-90+14^2+20^2=0
We add all the numbers together, and all the variables
x^2+506=0
a = 1; b = 0; c = +506;
Δ = b2-4ac
Δ = 02-4·1·506
Δ = -2024
Delta is less than zero, so there is no solution for the equation
