Hiiii friend,


P(X) = 2✓3X²-5X+✓3


=> 2✓3X²-3X-2X+✓3


=> ✓3X(2X-✓3) -1(2X-✓3)


=> (2X-✓3)(✓3X-1) = 0


=> (2X-✓3) = 0 OR (✓3X-1) = 0


=> X = ✓3/2 OR X = 1/✓3


✓3/2 and 1/3 are the two zeros of the given polynomial.


Let Alpha = ✓3/2 and Beta = 1/✓3



Relationship between the zeros and Coefficient.


Sum of zeros = (Alpha + Beta) = ✓3/2 + 1/✓3 = 3+2/2✓3 = 5/2✓3 = - (Coefficient of X/Coefficient of X²)


And,


Product of zeros = (Alpha × Beta) = ✓3/2 × 1/✓3 = ✓3/2✓3 = Constant term/Coefficient of X².




HOPE IT WILL HELP YOU....... :-)
