Solve 5+x by 5-x +5-x by 5+x =15/4
Answers
Answer:
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
