Answer 2

Hi friend ...

two consecutive integers can be defined as x and y
it is better to define it like y= x+2 that means it is unknown
x*y=195 . we can substitute it by y=x+2
x (x+2) = 195
x^2 +2x-195=0
now factorizing..
(x+15) (x-13) =0
so x= -15 and 13

since in the it is said as two consecutive odd no:
x= -15
y=x+2= -13
(-13)*(-15)= 195
y=x+2=15
13*15=195
so the consecutive odd number of 195 is 13 and 15 or -1 3and -15

hope it helps....
