Answer:
Numeric value of x satisfying the given equation is 1 / 25.
Step-by-step explanation:
Given equation : √x + x = 6 / 25
= > 25( √x + x ) = 25 × 6 / 25
= > 25√x + 25x = 6
= > 25x + 25√x - 6 = 0
= > 25( √x × √x ) + 25√x - 6 = 0
Now, let √x = a,
= > 25a^2 + 25a - 6 = 0
= > 25a^2 + ( 30 - 5 )a - 6 = 0
= > 25a^2 + 30a - 5a - 6 = 0
= > 25a^2 - 5a + 30a - 6 = 0
= > 5a( 5a - 1 ) + 6( 5a - 1 ) = 0
= > ( 5a - 1 )( 5a + 6 ) = 0
= > a = 1 / 5 or a = - 6 / 5
Taking positive value of a, so a = 1 / 5
Now, substitute the value of a,
= > √x = 1 / 5
= > x = 1 / 25
