Question

find the roots x+4upon x-4+x-4upon x+4=10upon 3

Answer 1

Answer:

[(X+4)/(X-4)]+[(X-4)/(X+4)]=10/3,

=>[(X+4)^2+(X-4)^2]/(X^2-16)=10/3,

=>(2X^2+32)/(X^2-16)=10/3,

=>6X^2+96=10X^2-160,

=>4X^2=256,

=>X^2=64,

=>X=+/-8.

Answer 2

Answer:

Step-by-step explanation:

[(X+4)/(X-4)]+[(X-4)/(X+4)]=10/3,

=>[(X+4)^2+(X-4)^2]/(X^2-16)=10/3,

=>(2X^2+32)/(X^2-16)=10/3,

=>6X^2+96=10X^2-160,

=>4X^2=256,

=>X^2=64,

=>X=+/-8.
