1. The problem is to simplify the phrase "shorten all of these" which implies reducing or simplifying expressions or terms. 2. Since no specific expressions are given, the general approach to shortening or simplifying algebraic expressions involves combining like terms, factoring, and reducing fractions. 3. Important rules include: combine like terms by adding or subtracting coefficients, factor common factors out of terms, and simplify fractions by dividing numerator and denominator by their greatest common divisor. 4. Without specific expressions, the best advice is to apply these rules to any algebraic expressions you have. 5. If you provide specific expressions, I can show step-by-step simplification.
