Respuesta :
Because it's a square root to the X, there's going to be 2 answers. After solving it I got x = 3,5
mmiinus 1 from both sides to get it equal to zero
x^2-8x+15=0
factor
what 2 numbers multiply to get 15 and add to get -8
-5 and -3
(x-5)(x-3)=0
set each to zero
x-5=0
x=5
x-3=0
x=3
x=3 and 5
x=4 is the answer
