Question

what is the solution of n2 - 49 = 0

Answer 1

Answer:

n = 7 , n = -7

Step-by-step explanation:

n^2 - 49 = 0 (Given)

n^2 = 49 (Add 49 on both sides)

n = plus or minus 7 (Square root on both sides)

Answer 2

Answer:  “ n  =  ± 7  ” .

_________________________________

       →  that is;   “ n = 7 ” ; or:  “ n = -7 ” .

Step-by-step explanation:

_________________________________

Given:

   n²  − 49 = 0 ;  Solve for "n" .

_________________________________

Add "49" to each side of the equation:

   →  n² − 49 + 49 = 0 + 49 ;

to get:

  →   n²   =  49 .

_________________________________

Now, take the "square root" of each side of the equation;

  to isolate "n" on one side of the equation;

   & to solve for "n" ;

_________________________________

  →  | √(n²) | = |√49|  ;

to get:

 →  n = ±  49 .
