Question

3 m² = 2m²-9
what is its general form
​

Answer 1

Answer:

m^2 + 9 = 0 , is the general form

m = +3i and -3i

Step-by-step explanation:

Given,

3m^2 = 2m^2 - 9

=> 3m^2 - 2m^2 - 9 = 0

=> m^2 + 9 = 0 , is the general form

On solving this,

=> m^2 = -9

=> m = √(-9)

We know that,

i = √-1

And, √-9 = √9 × √(-1)

Then,

m = +/- √9i

=> m = +3i and -3i

Hence, m = +3i and -3i.
