Respuesta :
So you have: (x - 5)^2 = 81
Take the square root of both sides.
x-5 = +/-9
x=5 +/-9
x=14,-4
Take the square root of both sides.
x-5 = +/-9
x=5 +/-9
x=14,-4
Answer:
solution of the given expression is ( 5 ±√81 ).
Step-by-step explanation:
( x - 5 )² = 81 is the expression and we have to get the solutions.
( x - 5 )² = 81
x - 5 = ±√81 ( if x² = 9 then x = ± 1 is the solution )
x = 5 ± √81
Therefore, solution of the given expression is ( 5 ±√81 ).
