Question

If x2 + 3mx +6 then the value of m is

Answer 1

Answer:

what is the value of x??

Answer 2

The value of m is $\pm \frac{2\sqrt{2}}{\sqrt{3}}$

Step-by-step explanation:

given equation:

$x^2 +3mx+6$

here a = 1 , b= 3m  and c = 6

therefore

discriminant = $b^2-4ac$

$3(m)^2-4(1)(6)\\\\9m^2-24 =0\\\\3m^2-8=0\\\\\text{dividing both sides by 3 }\\\\3m^2=8\\\\m= \pm \frac{2\sqrt{2}}{\sqrt{3}}$

hence , The value of m is $\pm \frac{2\sqrt{2}}{\sqrt{3}}$
