Chapter 6: Q 64E (page 589)

In the following exercises, factor each trinomial of the form $x^{2} + b x + c$ .
$b^{2} + 14 b + 48$

Short Answer

Expert verified

The factors are $(b + 6) (b + 8)$ .

Step by step solution

Step 1. Writing the expression

Write the factors as two binomials with first terms $b$ .

localid="1644544130598" $(b) (b)$ .

Step 2. Finding the factors

We need to find two numbers whose product is $48$ and sum is $14$ .

Factors of $48$	Sum of factors
$1, 48$	$49$
$2, 24$	$26$
$3, 16$	$19$
$4, 12$	$16$
$6, 8$	14

Thus $6, 8$ are the correct factors.

Thus, the factorization of the trinomiall is localid="1644542220674" $(b + 6) (b + 8)$ .

Step 3. Check

Multiply the factorization to get the trinomial again.

$(b + 6) (b + 8) = b^{2} + 8 b + 6 b + 48 (b + 6) (b + 8) = b^{2} + 14 b + 48$

Thus, the obtained factorization is correct.
