Chapter 7: Q. 84 (page 832)

In the following exercises, factor each trinomial of the form $x^{2} + b x + c$
$v^{2} - 2 v - 3$

Short Answer

Expert verified

The factorization of $v^{2} - 2 v - 3$ is $(v + 1) (v - 3)$

Step by step solution

Step 1. Given information

Given expression is $v^{2} - 2 v - 3$

Step 2. Find the last terms of the binomials

Factor out the expression:

Factors of -3	Sum of factors
1,-3	1+(-3)=-2

Step 3. factorization

use $1$ and $- 3$ as the last terms of the binomials.

$v^{2} - 2 v - 3 = (v + 1) (v - 3)$

Step 4. Check

$(v + 1) (v - 3) = v^{2} + v - 3 v - 3 = v^{2} - 2 v - 3$
