Solutions

Chapter 1.3, Problem 56E
To determine

To calculate: The simplified value of the expression (h2+1+1)(h2+11) .

Expert Solution

Answer to Problem 56E

The value of the expression (h2+1+1)(h2+11) is h2 .

Explanation of Solution

Given information:

The expression (h2+1+1)(h2+11) .

Formula used:

The special product formula of difference of squares to multiply the algebraic expressions is mathematically expressed as,

  (A+B)(AB)=A2B2

Calculation:

Consider the given expression (h2+1+1)(h2+11) .

Recall the special product formula of difference of squares to multiply the algebraic expressions is mathematically expressed as,

  (A+B)(AB)=A2B2

Here, A=h2+1 and B=1 .

Apply it,

  (h2+1+1)(h2+11)=(h2+1)2(1)2=h2+11=h2

Thus, the value of the expression (h2+1+1)(h2+11) is h2 .
