Asked by Sabrina
This is the problem you helped me with. I was curious, do I write the solution set as (1 + i3ã3)/2,
(1-i3ã3)/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 } ã-27)/2
Your answer is an imaginary number or called a complex number, you could rewrite is as
x = (1 } 3ã3 i)/2
(1-i3ã3)/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
