Q. Solve the equation.x+32x−1+x−31−2x=x2−9(4−3x)
Identify Common Denominator: Identify the common denominator for the two fractions.The denominators are (x+3) and (x−3). The common denominator will be the product of these two, which is (x+3)(x−3) or x2−9.
Rewrite with Common Denominator: Rewrite each fraction with the common denominator.(2x−1)/(x+3) becomes ((2x−1)(x−3))/(x2−9) and (1−2x)/(x−3) becomes ((1−2x)(x+3))/(x2−9).
Expand Numerators: Expand the numerators of both fractions.For the first fraction: (2x−1)(x−3)=2x(x)−2x(3)−1(x)+1(3)=2x2−6x−x+3=2x2−7x+3.For the second fraction: (1−2x)(x+3)=1(x)+1(3)−2x(x)−2x(3)=x+3−2x2−6x=−2x2−5x+3.
Combine over Common Denominator: Combine the expanded numerators over the common denominator.(2x2−7x+3−2x2−5x+3)/(x2−9).
Simplify Combined Numerator: Simplify the combined numerator. 2x2−7x+3−2x2−5x+3 simplifies to −12x+6.
Write Simplified Expression: Write the simplified expression.The simplified form of the expression is (−12x+6)/(x2−9).
Check Match with Given Expression: Check if the simplified expression matches the given expression on the right side of the equation.The given expression on the right side of the equation is (4−3x)/(x2−9). This does not match our simplified expression (−12x+6)/(x2−9).
