Answer:
10*5 or 25*2
Step-by-step explanation:
There are other answers but those involve decimals and I'm assuming they want whole numbers.
 
        
             
        
        
        
X² + 2x +3
If the discriminent Δ = b²-4.a.c <0 , that means the roots (or the zero value) are nit REAL Number (they are imaginary or complex) 
Δ = 2² - 4(1)3) = 4 - 12 = -8
since Δ = - 8 < 0 there are no real roots
