Simplify 8 over negative 4 ÷ negative 3 over 9. 6 –6 12 –12

What is the first step of an indirect proof of a number that is divisible by two

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 x = -2, then x 2-7x+10 equals a. 0 b.20 c.28
