Chapter 7: Q. 112 (page 832)

In the following exercises, factor each trinomial of the form $x^{2} + b x y + c y^{2}$
$c^{2} - 7 c d + 18 d^{2}$

Short Answer

Expert verified

The factorization of the expression $c^{2} - 7 c d + 18 d^{2}$ is not factorable.

Step by step solution

Step 1. Given information

Given expression is $c^{2} - 7 c d + 18 d^{2}$

Step 2. Find the last terms of the trinomials.

The factors of the expression:

Factors of 18	Sum of factors
-9, -2	-9 + (-2) = -11
-6, -3	-6 + (-3) = -9
-18, -1	-18 + (-1) = -19

Step 3. Factorization

Among the pair of numbers, there are no pairs with the sum of $- 7$

The given expression $c^{2} - 7 c d + 18 d^{2}$ is not factorable, because the trinomial is prime.
