To find: value of x Given: We know Let Therefore, Therefore, Squaring both sides, ⇒ x 2 – 64 = 225 ⇒ x 2 = 289 ⇒ x = ± 17 Therefore, x = ±17 are the required values of x.

Solve for x:

To find: value of x

Given:

We know

Let

Therefore,

Squaring both sides,

⇒ x² – 64 = 225

⇒ x² = 289

⇒ x = ± 17

Therefore, x = ±17 are the required values of x.
