Answer:
v — Prove that (ax + b)/(cx + d) is irrational if and only if ad = bc. ... If b = 0, we have (ax + b)/(cx + d) = 0 is rational; if c = 0, since ... nonzero integers m, n ∈ Z. Then we have ... Proof. We prove by induction. When n = 1, both sides are 1/2 hence the ... So there are less than (k + 1)(2k + 1)k+1 (actually muc

Answer: -2(x²+22x+40)
Step-by-step explanation:
When you factor an expression, you are taking out a common factor between the terms. A common factor we can take out is -2 or 2.
-2(x²+22x+40)
2(-x²-22x-40)
Both of these answers work, but we can also take out a -1, therefore, our factor is -2(x²+22x+40). Also, it looks nicer with more positive terms than negative.
