|x + 4| = 2
so it means 2 different eqns

x + 4 = 2     or     x + 4 = -2

Answer:

First picture , x=-6 and x=-2

Step-by-step explanation:

1. The idea is isolate x, hence we need to get rid of the +4 and the absolute value from the left side. To get rid of the absolute value, we need to set the right side as positive and negative.

x+4= +2    \\\\x+4=-2

2. Once we get rid of the absolute value, from each equation we solve for x. In the first equation we subtract 4 from both sides:

x=2-4\\x=-2

3. From the second equation, we subtract 4 from both sides

x=-2-4\\x=-6

In conclusion, we get two solutions that meet the initial equality

Without using a division or multiplication operator and without using iteration , define a recursive method named product that a
Fantom [35]

I will be using the language C++. Given the problem specification, there are an large variety of solving the problem, ranging from simple addition, to more complicated bit testing and selection. But since the problem isn't exactly high performance or practical, I'll use simple addition. For a recursive function, you need to create a condition that will prevent further recursion, I'll use the condition of multiplying by 0. Also, you need to define what your recursion is.
To wit, consider the following math expression 
 f(m,k) = 0 if m = 0, otherwise f(m-1,k) + k 
 If you calculate f(0,k), you'll get 0 which is exactly what 0 * k is. 
 If you calculate f(1,k), you'll get 0 + k, which is exactly what 1 * k is.   
 So here's the function   
 int product(int m, int k) 
 { 
  if (m == 0) return 0; 
  return product(m-1,k) + k;  
}
