If 5x=-20 then it would be

adding 2 and subtracting 2 they cancel out so its

and if you subtract 2 from negative 18 it is negative 20 so it is true
Two numbers that multiply to -2 could be
-1 and 2
Or
-2 and 1.
Since -1+2=1, -1 and 2 are the numbers you are looking for.
Hope this helps!
I don’t feel like doing it but I we’ll tell you how to do it you multiply it by 3 so 6 x 3 equals 18 just in negative do 18 x 3 equal 54 so every other on is a negative it’s Simone
N(2n+6)-(n²-1)= 2n²+6n-n²+1=n²+6n+1
