Solutions

Chapter 1.3, Problem 106E
To determine

To calculate: The factor of the expression x2+10x+25 .

Expert Solution

Answer to Problem 106E

The factor of the expression x2+10x+25 is (x+5)2 .

Explanation of Solution

Given information:

The expression x2+10x+25 .

Formula used:

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

  X2+2XY+Y2=(X+Y)2

Calculation:

Consider the given expression x2+10x+25 .

Rewrite it as,

  x2+10x+25=(x)2+2(x)(5)+(5)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=x and Y=5 .

  x2+10x+25=(x)2+2(x)(5)+(5)2=(x+5)2

Thus, the factor of expression x2+10x+25 is (x+5)2 .
