When x = 3 and y = 5, by how much does the value of 3x2 – 2y exceed the value of 2x2 – 3y ?

When x = 3 and y = 5, by how much does the value of 3x2 – 2y exceed the value of 2x2 – 3y ?
\(When\; x=3\; and \;y=5\\ 3x^2-2y=3*9-10=27-10=17\\ and\\ 2x^2-3y=2*9-15=18-15=3\)
So the question becomes
By how much does 17 exceed 3
The answer is 17-3=14
