Question

x²-9/x+3=4/7 find the value of x​

Answer 1

Answer:

Given equation :  

We can factorize x^2 - 3^2 by the identity a^2 - b^2 = ( a + b )( a - b ) where we can assume a as x and b as 3. So, x^2 - 3^2 = ( x + 3 ) ( x - 3 ).

( x - 3 ) =  

7( x - 3 ) = 4

7x - 21 = 4

7x = 4 + 21

7x = 25

x = 25 / 7

Therefore the value of x satisfying the equation is 25 / 7 .
