The positive root ofisa)3b)4c)5d)7Correct answer is option 'C'. Can yo...
Hi ,
The right answer is B because: -
√( 3x^2 + 6 ) = 9
Do the square bothsides of the
Equation.
=} 3x^2 + 6 = 81
=} 3x^2 = 81 - 6
=} 3x^2 = 75
Divide bothsides with 3
=} 3x^2 / 3 = 75/ 3
=} x^2 = 25
Now ,
=} x = sqrt ( 25 )
=} x = + or - 5
But we need pisitive root ,
therefore ,
=} x = 5
I hope this help you
That's all🙂

√(3x²+6)=9 => 3x²+6=9² => 3x²+6=81 => 3x²=81-6 => 3x²=75 => x²=75÷3 => x²=25 => x=√25 => x=±5 Hence, positive root of the given equation is 5.
