Answer 4

factorizes as well: a number that I added or subtracted as a result of the number of medium and found the same numbers to be multiplied as a result give me the expression that in this case was 21
signs depend on the original expression
a= -3 b= -7
-7-3= 10
-7*-3=21
in this case= (t-a ) (t-b)
