Y=x2+x-2 x+y=1
If(x, y)is a solution of the system of equtions abpve which of the following is possible value of xy?

The equations are :

y=x²+x-2

x+y=1⇒ y= 1-x

multiply(y=1-x) by -1 then add it to y= x²+x-2

you get : x²+x-2+x-1=0⇒ x²+2x-3 = 0

let Δ be the dicriminat of this equation :

a= 1b= 2c= -3

Δ = 2²-4*1*(-3)= 16

so this equation has two solutions

x= (-2-4)/2 = -3  or  x=(-2+4)/2 = 1

then :

if x= -3 y= 4   y= 1+3 if x = 1 y= 0

now the possible solutions are (-3,4) and (1,0)

the possible values of xy are :

-12 : -3*4= -120 : -3*0= 0 4 : 4*1= 4 0 : 1*0=0

so xy could be : 0 or 4 or -12

The whale was a missile blasting from beneath the surface.  2.) a majestic whale leapt skyward before diving back into the sea.    these are both figurative language. this is so because the whale in sentence "1" was not actually a missile, nor was it actually blasting. now, for sentence "2", a whale can not actually "leap".
