Answer:
C and D
Step-by-step explanation:
Given
(3x - 5)² = 19 ( take the square root of both sides )
3x - 5 = ± [tex]\sqrt{19}[/tex] ( add 5 to both sides )
3x = ± [tex]\sqrt{19}[/tex] + 5 ( divide both sides by 3 )
x = [tex]\frac{+/-\sqrt{19}+5 }{3}[/tex]
x = [tex]\frac{-\sqrt{19}+5 }{3}[/tex] → C
x = [tex]\frac{\sqrt{19}+5 }{3}[/tex] → D
