Answer:
Prime
Step-by-step explanation:
x² + 20x − 36
You must find a pair of numbers that multiply to give -36 and add to give +20.
The likely candidates are 2 and 18, and they must have opposite signs to give a negative product.
+2 × (-18) = -36; +2 + (-18) =   -16
 -2 ×   18  = -36;  -2 +     8   = +16
Neither combination gives +20 as the sum.
The expression can't be factored with rational numbers.
The expression is prime.
