Chapter 6: Q 178 (page 603)

In the following exercises, factor completely using the difference of squares pattern, if possible.
$121 - 25 s^{2}$

Short Answer

Expert verified

The complete factor of trinomial $(11 - 5 s) (11 + 5 s)$

Step by step solution

Step 1. Given information

Consider the given trinomial.

$121 - 25 s^{2}$

Step 2. Formula used

$a^{2} - b^{2} = (a + b) (a - b)$

Step 3. Write the trinomial as squares.

Write the trinomial as perfect squared form.

$121 - 25 s^{2} = 11^{2} - {(5 s)}^{2}$

Write them as product of conjugate.

$11^{2} - {(5 s)}^{2} = (11 - 5 s) (11 + 5 s)$
