Question

Which of the following are solutions to the equation below?

(3x - 5)^2 = 19
A. x= √19+5/3
B. x= -√14/3
c. x= - √19+5/3
D. X= √19+5/3
E x=-√19+5/3
F. x=√14/3​

Answer 1

C and D

Explanation:

Answer 2

C and D

Explanation:

Given

(3x - 5)² = 19 ( take the square root of both sides )

3x - 5 = ±
`√(19)` ( add 5 to both sides )

3x = ±
`√(19)` + 5 ( divide both sides by 3 )

x =
`(+/-√(19)+5 )/(3)`

x =
`(-√(19)+5 )/(3)` → C

x =
`(√(19)+5 )/(3)` → D
