One thing before we start :)
AS you can see both numbers after equation have to be negative,
also we know that 2 same numbers have to add up to -12 and those 2 number after multiplication have to be equal -28
Some theory:
We know that any number which is not negative multiplied by negative will result in negative result, to make it more clear
[tex](+)*(-)=(-)[/tex]
but
[tex](-)*(-)=(+)[/tex]
we have 2 unknown numbers, let's say it's [tex]x[/tex] and [tex]y[/tex]
[tex]x+y=-12[/tex]
[tex]x*y=-28[/tex]
for [tex]x=2[/tex]
for [tex]y=-14[/tex]
[tex]2+(-14)=2-14=-12[/tex]
[tex](2)*(-14)=-28[/tex]
So your answer is 2 and -14 ;)
