Question

please explain. Solve the equation using the quadratic formula. 6/x+6/x+9=1

Answer 1

6 6
--- + ----- = 1 so the common denominator will be x(x+9)
x x+9

6(x+9) +6x
------------ = 1(x)(x+9) / (x(x+9)
x(x+9)

6x+54 +6x = x(x+9)

12x +54 = x^2 +9x

x^2 +9x -12x -54 =0

x^2 -3x -54 =0

(x-9)(x+6) =0

x-9=0
x=9

x+6=0
x=-6

hope this will help you
