Identify Common Denominator: Identify the common denominator for the fractions on the left side of the equation.The common denominator for the fractions (2x−1)/3 and (1−2x)/(x−3) is 3(x−3).
Rewrite with Common Denominator: Rewrite each fraction with the common denominator.(2x−1)/3×(x−3)/(x−3)+(1−2x)/(x−3)×3/3=((4−3x))/(x2−9)This gives us ((2x−1)(x−3))/3(x−3)+3(1−2x)/3(x−3).
Simplify Numerators: Simplify the numerators of the new fractions.3(x−3)(2x−1)(x−3)+3(x−3)3(1−2x)= 3(x−3)2x2−6x−x+3+3(x−3)3−6x= 3(x−3)2x2−7x+3+3(x−3)3−6x
Combine Numerators: Combine the numerators over the common denominator.(2x2−7x+3+3−6x)/3(x−3)= (2x2−13x+6)/3(x−3)
Factor Denominator: Notice that the right side of the equation has the denominator x2−9, which factors to (x+3)(x−3). We can now equate the numerators since the denominators are the same. (2x2−13x+6)=(4−3x)
Solve Equation: Solve the equation (2x2−13x+6)=(4−3x) by moving all terms to one side.2x2−13x+6−4+3x=02x2−10x+2=0
Simplify Equation: Simplify the equation by dividing all terms by 2x2−5x+1=0.
Use Quadratic Formula: This is a quadratic equation, which can be solved by factoring, completing the square, or using the quadratic formula. However, this equation does not factor nicely, so we will use the quadratic formula.x=2(1)−(−5)±(−5)2−4(1)(1)x=25±25−4x=25±21
