Question 879740: x+4=-4/x
Multiply everything by the LCD which x
x(x+4)= x(-4/x)
x^2+4x = -4
Add 4 to both sides of the equation
x^2+4x+4=-4+4
x^2+4x+4=0
Factor into two binomials
(x+2)(x+2)
set both equal to 0 and solve for x
x+2 =0 x+2=0
in both equation subtract 2 on both sides
x+2-2=0-2
x= -2
x+2-2=0-2
x= -2
Therefore x= -2
