(3/5) * 65
3*(65/5)
3*13
39
it would be 315. The simplest way to doing this would be by, first , doubling the number to make 252 which would add up to be 80%, and then divide 126 by 2 to get 63 which would be 20% ad by adding them all together you would get 315, which is equal to 100%.
Answer:
x = 1+√3 i/2 and x = 1-√3 i/2
Step-by-step explanation:
Given the expression x^2 - x+ 1, we are to factorize the expression as shown;
x^2 - x+ 1,
using the general formula
x = -(-1)±√1²-4(1)/2(1)
x = 1±√1-4/2
x= 1±√-3/2
x = 1±√3 i/2
Hence the required value of x are x = 1+√3 i/2 and x = 1-√3 i/2
