Solutions

Chapter 1.3, Problem 107E
To determine

To calculate: The factor of the expression 4x2+4xy+y2 .

Expert Solution

Answer to Problem 107E

The factor of the expression 4x2+4xy+y2 is (2x+y)2 .

Explanation of Solution

Given information:

The expression 4x2+4xy+y2 .

Formula used:

The special factoring formula of perfect square which is expressed as,

  X2+2XY+Y2=(X+Y)2

Calculation:

Consider the given expression 4x2+4xy+y2 .

Rewrite it as,

  4x2+4xy+y2=(2x)2+2(2x)(y)+(y)2

Recall the special factoring formula of perfect square which is expressed as,

  X2+2XY+Y2=(X+Y)2

Here, the values of X and Y are X=2x and Y=y .

  4x2+4xy+y2=(2x)2+2(2x)(y)+(y)2=(2x+y)2

Thus, the factor of expression 4x2+4xy+y2 is (2x+y)2 .
