Question

x+y= -27 and xy= -160 find x =?

Answer 1

hope it helps you out

Answer 2

x + y = - 27
x = - ( y + 27 )
xy = - 160
y( y + 27 ) = 160
y^2 + 27y - 160 = 0
y^2 + 32y - 5y - 160 =0
y(y + 32 ) -5 ( y + 32 ) = 0
(y - 5 ) ( y + 32 ) = 0
y = 5 & - 32
if y = 5 then x =  - 32
if y = -32 then x = 5
