To find: value of x Formula Used: Given: LHS Therefore, Taking tangent on both sides, we get ⇒ 12 = 2x 2 – 6 ⇒ 2x 2 = 18 ⇒ x 2 = 9 ⇒ x = 3 or x = -3 Therefore, x = ±3 are the required values of x.

Solve for x:

To find: value of x

Formula Used:

Given:

LHS

Therefore,

Taking tangent on both sides, we get

⇒ 12 = 2x² – 6

⇒ 2x² = 18

⇒ x² = 9

⇒ x = 3 or x = -3

Therefore, x = ±3 are the required values of x.
