localid="1649152716117" $x^{2} + x + 5$

Short Answer

Expert verified

The factorization of the expression $x^{2} + x + 5$ is not factorable.

Step by step solution

Step 1. Given information

Given expression is $x^{2} + x + 5$

Step 2. Find the last terms of the binomial.

The factor of expression:

The factor of 5	Sum of factor
1, 5	1 + 5 = 6
5, 1	5 + 1 = 6

Step 3. Factorization

Among the pair of numbers, there are no pairs with the sum of $1$ .
