Question

Find two numbers whose sum is -16 and product is +36

Answer 1

Answer:

if we consider x y as two nos.

Step-by-step explanation:

x+y=-16...1

xy=36....2

x=36/y...3

x+36/y=-16.....4(put 3 in 1)....find x y ..it's simple...u can do it by our own...pls follow me and Mark it as branliest

Answer 2

Answer:

Y=18,X=2

Step-by-step explanation:

let the no.s be x and y

then,

x+Y=-16-EQ 1

XY=+36-EQ2

from EQ1

x=16+y

substitute in eq 2

[16+y][y]=+36

16y+y^2=36

y^2+16y-36=0

by factorization

y^2+[18-2]Y-36=0

Y^2+18Y-2Y-36=0

Y[Y+18]-2[Y+18]=0

Y=2 ,

XY=36

X=36/Y

X=36/2

X=18
