The expression in the image is:

$(4x^2 - 2) - (6x + 1) - (x^2 - 5)$

Let's simplify it step by step:

1. Distribute the negative signs through each term inside the parentheses: $4x^2 - 2 - 6x - 1 - x^2 + 5$

2. Combine like terms:

   • For the $x^2$ terms: $4x^2 - x^2 = 3x^2$
   • For the constant terms: $-2 - 1 + 5 = 2$
   • For the $x$ term: $-6x$

So, the simplified expression is:

$3x^2 - 6x + 2$
