a. m. what time did rick start his coffee break?

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

Which shows the correct solution of the equation 1/2a+2/3b=50, when b=30?
