Factor: $x^{2} - 7 x y - 10 y^{2}$

Short Answer

Expert verified

The factorization of $x^{2} - 7 x y - 10 y^{2}$ is not factorable.

Step by step solution

Step 1. Given information

Given expression is $x^{2} - 7 x y - 10 y^{2}$

Step 2. Find the last terms of the trinomial.

The factor of the expression:

The factor of - 10	Sum of factor
1, - 10	1 + ( - 10) = - 9
2, - 5	2 + ( - 5) = - 3
-2, 5	- 2 + ( 5) = 3
- 1, 10	- 1 + ( 10) = 9

Step 3. Factorization

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

The given expression $x^{2} - 7 x y - 10 y^{2}$ is not factorable because it is a prime.
