Solutions

Chapter 1.3, Problem 105E
To determine

To calculate: The factor of the expression t26t+9 .

Expert Solution

Answer to Problem 105E

The factor of the expression t26t+9 is (t3)2 .

Explanation of Solution

Given information:

The expression t26t+9 .

Formula used:

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

  X22XY+Y2=(XY)2

Calculation:

Consider the given expression t26t+9 .

Rewrite it as,

  t26t+9=(t)22(t)(3)+(3)2

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

  X22XY+Y2=(XY)2

Here, the values of X and Y are X=t and Y=3 .

  t26t+9=(t)22(t)(3)+(3)2=(t3)2

Thus, the factor of expression t26t+9 is (t3)2 .
