Chapter 1.4, Problem 61E
To determine

To calculate: The expression x+2x1x3x2x+2

Expert Solution

Answer to Problem 61E

  x+2x1x3x2x+2=4x7(x+2)(x1)(x2)

Explanation of Solution

Given information:

Given expression is x+2x1x3x2x+2

Consider the expression as x+2x1x3x2x+2

Now,

  x+2x1x3x2x+2=(x+2)(x2)(x3)(x1)(x1)(x2)x+2=x24(x2x3x+3)(x+2)(x1)(x2)=x24(x24x+3)(x+2)(x1)(x2)=x24x2+4x3(x+2)(x1)(x2)=4x7(x+2)(x1)(x2)

Therefore, x+2x1x3x2x+2=4x7(x+2)(x1)(x2)
