Answer:
w⁴ - 36
=> ( w² )² - ( 6 )²
=> ( w² + 6 ) ( w² - 6 )
=> w² + 6 = 0 and w² - 6 = 0
=> w = √-6 and w = √6
Hi!
Xian - 60 stamps
Kai - 76 stamps
60 + 12 = 72
76 + 8 = 84
72 + 12 = 84
84 + 8 = 92
84 + 12 = 96
92 + 8 = 100
96 + 12 = 108
100 + 8 = 108
After how many months will Xian and Kai have the same number of stamps?
4 months
How many stamps will each have?
108 stamps
First one is 33y^3-22y^2-27y+18
Second one is -3a^4-20a^2 x^2+7x^4
I hope this helps you :)
