Question

Решите систему неравенств 
{(5x+1)^2=6y
{(x+5)^2=6y

Answer 1

6Y = 6Y 
( 5X + 1)^2 = ( X + 5)^2 
25X^2 + 10X + 1 = X^2 + 10X + 25 
24X^2 = 24 
X^2 = 1 
X1 = + 1 
X2 = - 1 
---------------------------------
( X + 5)^2 = 6Y 
6Y = ( 1 + 5)^2 
6Y = 36 
Y1 = 6 
----------
( - 1 + 5)^2 = 6Y 
6Y = 16 
Y2 = 16/6 = 8/3 = 2 2/3 
--------------------------------
Ответ ( 1 ; 6 ) ; ( - 1 ; 2 2/3 )
