Question- Write the standard equation of the circle with center (-4,5) that passes through the point (-4,7)

Find the solution set of this inequality. select the correct graph. |8x+16|> 16

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

Could somebody me with this radical simplification?
