Answer:
The two numbers can be -12 and 11, or 11 and -12.
Step-by-step explanation:
xy=-132
x+y=-1
-------------
x=-1-y
(-1-y)y=-132
-y-y^2=-132
-y^2-y-(-132)=0
-y^2-y+132=0
y^2+y-132=0
factor out the trinomial,
(y-11)(y+12)=0
zero property,
y-11=0, y+12=0,
y=0+11=11,
y=0-12=-12
x+11=-1 & x+(-12)=-1
x=-1-11=-12
x=-1-(-12)=-1+12=11
Y=2/(x^2 +3)
g(x) = x^2 + 3 and f(x) = 2/x
fog(x) = f[g(x)]
= f(x^2 + 3)
= 2/(x^2 + 3)
the scientific notation for 0.089 is 0.089 = 8.9 x 10-2
