Question

Which XXX will complete the code to calculate  c = a2 + b2 + 2ab ?

public class MyCalc {
   public int powerSq(int num) {
      return num * num;
   }
   public int mult(int a, int b) {
      return a * b;
   }
   public static void main(String [] args) {
      int a = 1;
      int b = 2;
      int c;
      MyCalc myCalc = new MyCalc();
      XXX  
   }
}

answers:

1) c = powerSq(a) + powerSq(b) + 2 * mult(a);
2) c = powerSq(a, b) + powerSq(a, b) + 2 * mult(a, b);
3) c = myCalc.powerSq(a) + myCalc.powerSq(b) + 2 * myCalc.mult(a);
4) c = myCalc.powerSq(a) + myCalc.powerSq(b) + 2 * myCalc.mult(a, b);
