Chapter 8.2, Problem 68PE

For Exercises 67-68, find the constants $A$ and $B$ so that the two polynomials are equal. (Hint: Create a system of linear equations by equating the constant terms and by equating the coefficients on the $x$ terms and $x^2$ terms.)

$3x^2+37x-82=A{x}^2+Ax-12A+3B{x}^2-10Bx+3B+3C{x}^2+11Cx-4C$
