Q. 34.7( 3 Votes )

Determine whether x = √3 and x = —2√3 are solutions of the equation x2 – 3√3x + 6 = 0

Answer :

Put both the values of x in the equation.


When x = √3


(√3)2 –3√3(√3) + 6 = 0


3 – (3)3 + 6


3 – 9 + 6


9 – 9


= 0


Therefore, it is the solution to the equation.


When x = –2√3


(–2√3)2 –3√3(–2√3) + 6 = 0


12 + 18 + 6


= 36


Therefore, it is not the solution to the equation.
