The answer is (5n+6)(n-2)
Ok, so if a zero is at r1, then a factor is (x-r1)
since there are no other roots, it must be only taht root
3rd degree so reaise it to the 3rd power
(x-r1)³
and the root is at x=-3
(x-(-3))³
(x+3)³
answer is f(x)=(x+3)³
also could be x³+27 where it factors to one real root and 2 complex roots
So we are assuming that the three shirts have equal price. Let the price of one shirt be a.
In store A:
the cost is (a+a+a) -(25/100)a=3a-0.25a=2.75a
In store B:
the cost is : a+a+50/100 a =a+a+0.5a=2.5a
In store C:
the cost is
[a-(10/100)a]+[a-(10/100)a]+[a-(10/100)a]=[a-0.1a]+[a-0.1a]+[a-0.1a]
=0.9a+0.9a+0.9a= 2.7a
thus the cost of buying the shirts from stores A, B and C is:
2.75a, 2.5 a and 2.7 a respectively.
the best deal, is buying from store B, where the cost is the lowest: 2.5a.
Answer: store B
