The value of x in the equation \frac{4x}{x - 1} - \frac{5x}{x -2} = \frac{2}{x^2 - 3x + 2} is x = -1 or x = -2

<h3>How to solve the equation?</h3>

The equation is given as:

\frac{4x}{x - 1} - \frac{5x}{x -2} = \frac{2}{x^2 - 3x + 2}

Start by taking the LCM

\frac{4x(x - 2) - 5x(x - 1)}{(x - 1)(x -2)} = \frac{2}{x^2 - 3x + 2}

Expand the denominator

\frac{4x(x - 2) - 5x(x - 1)}{x^2 -3x +2} = \frac{2}{x^2 - 3x + 2}

Cancel out the common factor

4x(x - 2) - 5x(x - 1)= 2

Expand

4x^2 - 8x - 5x^2 + 5x = 2

Evaluate the like terms

-x^2 - 3x = 2

Rewrite as:

x^2 + 3x + 2 = 0\\

Expand

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

Factorize

x(x + 2) + 1(x + 2) = 0

Factor out x + 2

(x + 1)(x + 2) = 0

Solve for x

x = -1 or x = -2

Hence, the value of x in the equation \frac{4x}{x - 1} - \frac{5x}{x -2} = \frac{2}{x^2 - 3x + 2} is x = -1 or x = -2

Vertical angles are equal.

4x + 12 = 6x - 10

-4x -4x

12 = 2x - 10

+10 +10

22 = 2x

Divide each side by 2
