I will answer 2 versions of this question

Version 1: in which I assume the 2 in this expression was meant to be an exponent

(-5)[3-(x+5)^2]

Evaluate the inner term first to give
(-5)[3 - (x^2+10x+25)]

Simplify by combining the values inside the brace brackets that do not involve the variable x
(-5)[-x^2-10x-22]

Multiply the terms inside the brace brackets by the term outside the brace brackets
5x^2 +50x +110

Version 2: assuming the 2 in the expression was meant as a multiplier of the sub expression

(-5)[3-(x+5)*2]

Evaluate the inner product
(-5)[3 - (2x+10)]

Combine the constant terms inside the brace brackets
(-5)[-2x - 7]

Multiply the terms inside the brace brackets by the term outside the brace brackets
10x + 35
