Question

pls answer
x^2-9/x+3=5​

Answer 1

Answer:

Step-by-step explanation:

Given problem is :      ( x²  - 9) / (x + 3)  = 4 /7

Cross multiply the terms:

   7 x² - 7*9 = 4x + 4*3

   7 x² - 4 x - 75 = 0

                                    7 * 3 * 5 * 5  = 21 * 25  difference is 4

   7 x² - 25 x + 21 x - 75 = 0

   x (7x - 25) + 3 (7 x - 25) = 0

    (x + 3) (7 x - 25) = 0

   x = -3    or    x = 25/7
