Chapter 6: Q. 390 (page 635)

In the following exercises, factor completely using the difference of squares pattern, if possible.
$25 p^{2} - 1$

Short Answer

Expert verified

The Factored form of given polynomial is $(5 p + 1) (5 p - 1)$ .

Step by step solution

Step 1. Given Information

We are given a polynomial,

$25 p^{2} - 1$

The formula used for factoring using the difference of squares pattern is,

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

Step 2. Factorizing the polynomial

The given polynomial can be written as,

$25 p^{2} - 1 = {(5 p)}^{2} - 1^{2}$

Using $a^{2} - b^{2} = (a + b) (a - b)$ , we get

$25 p^{2} - 1 = (5 p + 1) (5 p - 1)$

Step 3. Checking the factorization by multiplying

Multiplying the factors, we get

$(5 p + 1) (5 p - 1) = 25 p^{2} - 1 {(5 p)}^{2} - 5 p + 5 p - 1 = 25 p^{2} - 1 25 p^{2} - 1 = 25 p^{2} - 1 L H S = R H S$

Hence the factorization is correct.
