-8

Explanation:

-5^2+3(5)+2=-5^2+3*5+2

Use the order of operations to figure out which operator to evaluate first.
Order of precedence:
1. Parenthesis
2. Exponent
3. Multiplication, Division (whichever comes first you evaluate)
4. Addition, Subtraction (whichever comes first you evaluate)

So looking at the expression, we must first evaluate the exponent.
=-25+3*5+2

Next, we do the multiplication operator.
=-25+15+2

Then, we do the addition operators.
=-10+2
=-8
