Solve by graphing. Round each answer to the nearest tenth.

6x^2 + 31x = 12

Proceed as in example 3 in section 6.1 to rewrite the given expression using a single power series whose general term involves xk. ∞ n(n − 1)cnxn − 2 n = 2 − 4 ∞ ncnxn n = 1 + ∞ cnxn n = 0

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)
