Expert Solution

Answer to Problem 23E

The simplified form of the expression is, 14x8

Explanation of Solution

Given information:

The expression is given as: 4xx24x+216x

Formula used:

The algebraic identity: a2b2=(ab)(a+b)

Calculation:

Consider the equation , 4xx24x+216x

Rewrite the equation, 4x(x2)(22)x+216x

Apply the identity in denominator, a2b2=(ab)(a+b) ,

And by split the denominator,

Therefore, the equation is,

  4xx24x+216x=4x(x2)(x+2)x+244x=14(x2)=14x8

Thus, the given expression is: 14x8
