Rational expressions like (2x+3)/(x²–x–2) can often be decomposed into simpler fractions. First factor the denominator (x²–x–2= (x–2)(x+1)), then express (2x+3)/( (x–2)(x+1) )= A/(x–2)+ B/(x+1). Solve for A and B by equating numerators. Partial fractions simplify integration, advanced calculus, or solving differential equations. This method also clarifies rational function structures in engineering or physics. Mastering partial fractions fosters powerful manipulations and easier expansions in multi-step algebraic or analytic tasks.
