Question

(C-5)2+2=16 Square root property

Answer 1

c = 5 ±
`√(14)`

Explanation:

given the equation

(c - 5)² + 2 = 16 ( subtract 2 from both sides )

(c - 5)² = 14 ( take square root of both sides )

`√((c-5)^2)` = ±
`√(14)` , that is

c - 5 = ±
`√(14)` ( add 5 to both sides )

c = 5 ±
`√(14)`

solutions are c = 5 -
`√(14)` , c = 5 +
`√(14)`
