Answer 2

Answer:

The roots of the quadratic equation are 3i & - 3i.

Step-by-step-explanation:

The given quadratic equation is 3m² = 2m² - 9.

We have to find the roots of this quadratic equation.

Now,

3m² = 2m² - 9

⇒ 3m² - 2m² = - 9

⇒ m² = - 9

⇒ m = ± √( - 9 )

⇒ m = ± √( - 1 * 9 )

⇒ m = ± [ 3 * √( - 1 ) ]

⇒ m = ± 3i

∴ The roots of the quadratic equation are 3i & - 3i.
