Solutions

Chapter 1.3, Problem 104E
To determine

To calculate: The factors of the expression 4t29s2 .

Expert Solution

Answer to Problem 104E

The factors of the expression 4t29s2 are 2t3s and 2t+3s .

Explanation of Solution

Given information:

The expression 4t29s2 .

Formula used:

The special factoring formula of difference of squares which is expressed as,

  A2B2=(A+B)(AB)

Calculation:

Consider the given expression 4t29s2 .

Rewrite it as,

  4t29s2=(2t)2(3s)2

Recall the special factoring formula of difference of squares which is expressed as,

  A2B2=(A+B)(AB)

Here, the values of A and B are A=2t and B=3s .

  4t29s2=(2t)2(3s)2=(2t3s)(2t+3s)

Thus, the factors of expression 4t29s2 are 2t3s and 2t+3s .
