(Distribute the minus sign of the subtrahend in each term.)
= 8r⁶s³ – 9r⁵s⁴ + 3r⁴s⁵ – 2r⁴s⁵ + 5r³s⁶ + 4r⁵s⁴
(Add or subtract like terms.)
= 8r⁶s³ – 5r⁵s⁴ + r⁴s⁵ + 5r³s⁶
(If you want to factor out, then...)
= r³s³ (8r³ – 5r²s + rs² + 5s³)
Answer:
I think it is this because it seems as if It is 2 separate equations.
a.x=9-2y/3
b.x=3+y/3
Find a counter example?
hmm
|a-b| finds the distance between a and b,
|a|-|b| finds the distance between a and b, such that |a|>|b|
ah ha
so we just need to find a and b such that b>a
b=10
a=5
|a-b|=|5-10|=|-5|=5
|a|-|b|=|5|-|10|=5-10=-5
5≠-5
tada
it is not true for all real numbers
if for all numers such that b>a, it is false
