Answer 2

$<b> <i> <u> Heya!! </b> </i> </u>$

_______________________________________________________________

✔Given Equation → 4x² + 9

The Equation can be rewritten as :-

→ 4x² - 9i² = 0

→ (2x)² - (3i)² = 0

=> ( 2x + 3i) (2x - 3i)

★ 2x + 3i = 0

=> 2x = -3i

$= > x = - \frac{ 3}{2} i$........(1)

★2x - 3i = 0

=> 2x = 3i

$= > x = \frac{3}{2} i$........(2)


•°• The above mentioned are the two possible values of x !

$<b> Identities Used ★ i² = -1 ★ a² - b² = ( a + b ) ( a - b) </b>$

[Note ] : I've solved the equation by using Complex Number system as there's no specific mention in the question!


$<u> Thanks !! </u>$
