Which of the following are solutions to the equation below? Check all that apply. (3x - 5)2 = 19 O A. x= 19+ olm B. x= 119 +5 I C. x= - 19 + D. x= _V14 3 O E. x= -19 +5 3 O F. X= 14 3

Respuesta :

Solution

[tex](3x-5)^2=19[/tex]

For this case we can take square root in both sides and we have:

[tex]3x-5=\pm\sqrt[]{19}[/tex]

And solving for x we got:

[tex]x=\frac{5\pm\sqrt[]{19}}{3}[/tex]

then the solutions for this case are:

B and E
