REDUCING EQUATIONS

Question

((x²-1)/x)-8((x²-1)/x)+15=0

Answer 1

 

x² - 1     - 8((x² - 1)  + 15 = 0

   x                  x

 

x² - 1 - 8(x² -1) + 15x = 0

 

x² -1 -8x² + 8 + 15x = 0

 

-7x² + 15x + 7 = 0

 

From here you can use quadratic equation to find values of x

I hope this helps. If it doesn't you can always post it again
