Question 4 Solve 2 + + 1= 0 x2 + x + 1 = 0 The above equation is of the form ax2 + bx + c = 0 Where a = 1 , b = 1 , c = 1 Here, x = ( ( ^2 4 ))/2 Putting values of a , b and c = ( 1 (1^2 4 1 1))/ (2 1) = ( 1 (1 4))/2 = ( 1 ( 3))/2 = ( 1 3 ( 1))/2 = ( 1 3 )/2 Thus, = ( 1 3 )/2. Next: Question 5 Important Deleted for CBSE Board 2024 ..., Because (a + 1) 2 = a, a + 1 is the unique solution of the quadratic equation x 2 + a = 0. On the other hand, the polynomial x 2 + ax + 1 is irreducible over F 4, but it splits over F 16, where it has the two roots ab and ab + a, where b is a root of x 2 + x + a in F 16. This is a special case of Artin–Schreier theory. See also, $ x^0+ x^1 + x^2 + \ldots + x^n$ This should be really simple I guess and I tried something but got to a dead end.
