If 3x^2+13=883x
2
+13=883, x, squared, plus, 13, equals, 88 and x>0x>0x, is greater than, 0, what is the value of xxx ?

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

If f(x)=2x-6 and g(x)=3x+9, find (f-g)(x)

Icould really use some with this question.
