Question

find zeroes of 2x square +6x+12​

Answer 1

HOLA MATE!!! ❤

HERE IS YOUR ANSWER:-

USING COMPLETING THE SQUARE METHOD:-

x²+ 3x + 6 = 0

x²+ (3/2)² +3x +6 = (3/2)²

{x+ (3/2)}² = 9/4 - 6

x + (3/2) = ±√15i /√4

x+(3/2) = ±√15i/2

x= ±√15i / 2 -(3/2)

x = ± √15i - 3 / 2..........(answer)

(underroot is used only with 15)

HOPE THIS HELPS.....
