# Problem KSimple Factoring

Ms. Alice was working on making some factoring homework for her students last week, where the students get questions in the form of $ax^2+bx+c$, and must rewrite the expression in the form $(dx+ e)(fx + g)$, where $a,b,c,d,e,f,g$ are integers. She is done making the questions, but wants someone to check them over to make sure the expressions are factorable.

The expression $ax^2+bx+c$ is factorable if and only if the expression $ax^2+bx+c$ is able to be successfully rewritten in the form $(dx+ e)(fx + g)$, where $a,b,c,d,e,f,g$ are integers.

To help Ms. Alice, you must check if each question is factorable!

## Input

The first line contains the number of test cases $0<n\le 100$. The next $n$ lines each consist of three space separated integers $0<a,b,c\leq 10^{8}$.

## Output

For each test case, output a line consisting of “YES” if factorable, and “NO” otherwise.

Sample Input 1 Sample Output 1

1 2 1
1 3 1
