Answer:

The solution of the equation is at x=1 and 2.

Step-by-step explanation:

Given : Equation \frac{1}{x+3}-\frac{1}{x-6} =\frac{9}{20}

To find : The solution of the equation?

Solution :

We solve the given equation by taking LCM of the denominator.

\frac{1}{x+3}-\frac{1}{x-6} =\frac{9}{20}

\frac{x-6-(x+3)}{(x+3)(x-6)}=\frac{9}{20}

\frac{x-6-x-3)}{x^2-6x+3x-18}=\frac{9}{20}

\frac{-9}{x^2-3x-18}=\frac{9}{20}

Cross multiply,

x^2-3x-18=\frac{-9\times 20}{9}

x^2-3x-18=-20

x^2-3x+2=0

Solve by middle term split,

x^2-2x-x+2=0

x(x-2)-1(x-2)=0

(x-2)(x-1)=0

x=1,2

Therefore, The solution of the equation is at x=1 and 2.
