How do I graph an equation?

If m 17 27 90 63 ** picture is attached

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

Before simplifying, how many terms are there in the expression 2x - 5y + 3 + x?
