Solve the equation n2 − 29 = 260 by using square roots.

umka2103 [35]

Answer:

Option A, $n =$ ± $17$

Step-by-step explanation:

<u>Step 1: Add 29 to both sides</u>

$n^2 - 29 = 260$

$n^2 - 29 + 29 = 260 + 29$

$n^2 = 289$

<u>Step 2: Square root both sides</u>

$\sqrt{n^2} = \sqrt{289}$

$n =$ ± $17$

Answer: Option A, $n =$ ± $17$
