Quadratic equation and variables

a 10 :

b 11 :

c 1 :

x f a x 2^* b x * + c + :

Solving the quadratic equation using solve function gives:

x f x solve 1 - 110 / - 21 mat

This compares with roots calculated using standard equation:

r b - b 2^4 a * c * - sqrt + 2 a * / b - b 2^4 a * c * - sqrt - 2 a * / 21 mat : 11 - 81 sqrt + 20 / 1181 sqrt + 20 / - 21 mat

r b - b 2^4 a * c * - sqrt + 2 a * / b - b 2^4 a * c * - sqrt - 2 a * / 21 mat : 0.1 - 1 - 21 mat
