What 2 numbers multiply to get -70 and add to get -33
--------
x*y = -70
x + y = -33
-----------------------
Substitute for "x" and solve for "y"::
(-33-y)*y = -70
33y + y^2 = 70
y^2 - 33y - 70 = 0
-------------------------
y = 35 so x = -2
or
y = 2 so x = -35
----------------------

let the numbers be x & y
xy = -70
x= -70/y
x+y = -33
-70/y +Y = -33
-70 +Y^2 = -33Y
y^2+33y -70 =0
y^2+35y-2y-70=0
y(y+35)-2(y+35)=0
(y+35)(y-2)=0
y=-35 OR y = 2
x= 2 OR -35
(2,-35) (-35,2)
