You can put this solution on YOUR website!

Given:
a = 2
b = 5
c = (-3)

Gives us:
+3%282%29%5E2+-+5+%2B+2%28-3%29

Following the Order of Operations (PEMDAS), since we have no operations inside parenthesis, we deal with the exponent first:
+3%282%29%5E2+-+5+%2B+2%28-3%29+ becomes +3%284%29+-+5+%2B+2%28-3%29+

Next, working from left to right, we do multiplication:
+3%284%29+-+5+%2B+2%28-3%29+ now becomes +12+-+5+%2B+%28-6%29+ or +12+-+5+-+6+

From +12+-+5+-+6+ I'll allow you to do the final two operations and bob's your uncle!
