Step-by-step explanation:
let 1st integer= x
let 2 integer= y
ATQ
x+y = -11
x= -11-y..(1)
x×y= -60
put value of x
(-11-y)×y= -60
-11y-y²= -60
-y²-11y+60 = 0
y²+11y-60 =0
y²+15y-4y-60=0
y(y+15)-4(y+15)=0
(y-4)(y+15)=0
y-4 =0 or y+15=0
y=4 y=-15
put value of y in eq (1)
if y=4
then value of x= -11-4=-15
if value of y= -15
then value of x= -11+15=4
