Question

36. If|x + 3) = 2 and (y + 8= 3 then find least value of xyl:
(A) 5
(B) -5
(C) 7

(D) 8​

Answer 1

Answer = 5

Step-by-step explanation:

For (X+3)=2 :-

X+3=+_2

X+3=2 OR X+3=-2

Therefore X=-1 or X=-5

For (Y+8)=3 :-

Y+8=+_3

Y+8=3 OR Y+8=-3

Therefore y= -5 or y=-11

So least value of (XY) :- X= -1 & Y= -5

Therefore (XY) = {(-1) (-5)}

(XY) = (5)

So, XY= 5
