Question

The roots of equation x2 – 4x + 13 = 0 are

(a) 2 + 3i, 2 + 3i (b) 2 – 3i, 2 – 3i (c) 2 + 3i, 2 – 3i (d) None​

Answer 1

Answer:

c  is the answer

Step-by-step explanation:

x2 - 4x+13 = 0

formula is =  (-b +or- root of( b2(square)-4ac)/2a

                =  (-(-4) -or+ root of (16-52))/2

                 = (4 -or+  root of (-36))/2

                 = ( 4 -or+  root of (36 i2(square))/2  (i2(square) = -1)

                 = ( 4 - 6i)/2 , (4 + 6i)/2

                  2 - 3i , 2 + 3i
