Math clarification Reiny
posted by Sabrina
This is the problem you helped me with. I was curious, do I write the solution set as (1 + i3ã3)/2,
(1i3ã3)/2
change it to the standard form first
x^2  x + 7 = 0
a=1, b=1, c = 7
x = (1 } ã(1  4(1)(7))/2
= (1 } ã27)/2
Your answer is an imaginary number or called a complex number, you could rewrite is as
x = (1 } 3ã3 i)/2
