**Simplifying and Evaluating the Expression**

To simplify and evaluate the expression x ( x *2 xy 2xyz ) 5xy for x=1, y=-1, z=-2, we will follow the order of operations (PEMDAS) and substitute the given values for x, y, and z.

Let's simplify the expression step by step:

Step 1: Substitute the given values x=1, y=-1, z=-2 into the expression.
x ( x *2 xy 2xyz ) 5xy
= 1 ( 1 *2 (1*(-1)) 2*1*(-2) ) 5*1*(-1)
= 1 ( 2 + (-1) + (-4) ) (-5)
= 1 ( -3 - 4 ) (-5)
= 1 ( -7 ) (-5)
= -7 (-5)

Step 2: Multiply -7 by -5.
-7 * (-5) = 35

Therefore, the simplified and evaluated value of the expression x ( x *2 xy 2xyz ) 5xy for x=1, y=-1, z=-2 is 35.

**Explanation:**

To simplify the given expression, we need to apply the order of operations (PEMDAS), which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

In the given expression, we have x ( x *2 xy 2xyz ) 5xy.

Step 1: We substitute the given values x=1, y=-1, z=-2 into the expression:
x ( x *2 xy 2xyz ) 5xy
= 1 ( 1 *2 (1*(-1)) 2*1*(-2) ) 5*1*(-1)

Step 2: We simplify the expression inside the parentheses using the order of operations:
= 1 ( 2 + (-1) + (-4) ) (-5)
= 1 ( -3 - 4 ) (-5)
= 1 ( -7 ) (-5)

Step 3: We multiply -7 by -5 to get the final result:
-7 * (-5) = 35

Therefore, the simplified and evaluated value of the expression x ( x *2 xy 2xyz ) 5xy for x=1, y=-1, z=-2 is 35.
