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#
