Solve the following equation a (x-1) = 2 (x + 1) (a is not equal to 0) the square of 1 / 2 (BX) = 0 (B is greater than 0)

Solve the following equation a (x-1) = 2 (x + 1) (a is not equal to 0) the square of 1 / 2 (BX) = 0 (B is greater than 0)

A (x-1) = 2 (x + 1) (a is not equal to 0)
ax-a=2x+2
(a-2)x=a+2
x=(a+2)/(a-2)
1 / 2 (BX) ^ 2 = 0 (b > 0)
bx^2=0
x=0
