Question

Solve the equation n2 − 29 = 260 by using square roots.
A. n = ±17
b. n = ±19
c. no real solutions
d. n = ±18

Answer 1

Answer:

Option A, $n =$ ± $17$

Step-by-step explanation:

Step 1:  Add 29 to both sides

$n^2 - 29 = 260$

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

$n^2 = 289$

Step 2:  Square root both sides

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

$n =$ ± $17$

Answer:  Option A, $n =$ ± $17$
