Need ! discuss how to convert the standard form of the equation of a circle to the general form. 50 points

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

What is the answer to this question? i'm a bit stumped. also how do i do it? 5(x - 4) = 2(x + 5)
