Question

(5+x)/(5-x)-(5-x)/(5+x)=3 3/4

Answer 1

Answer:

( 5 +x ) /( 5 - x ) - ( 5 + x ) / ( 5 + x ) = 15 / 4

( 5 + x )^2 -( 5 - x )( 5 + x ) / (5)^2 - (x)^2 =15 / 4

25 + x^2 + 10x - 25 + x^2 / 25 - x^2

= 15 / 4

2x^2 + 10 x / 25 - x^2 =

15 / 4

8x^2 + 40x = 375 - 15 x^2

=23x^2 + 40x - 375= 0

x( 23x + 40 ) - 375 = 0

min.value of "x"

23x + 40 = 0

23x = - 40

x = - 40 / 23
