The Rules of Adding and Subtracting Rational Numbers Adding Same Signed Numbers - We make sure to add their absolute values. Your final sum should have the same sign as your addends. Example: 4 + 7 = 11. Both addends are positive values, the sum must be too. Example: -6 + -2 ...
Example 5: Subtracting Rational Expressions Subtract the rational expressions: 6x2+4x+4−2x2−46x2+4x+4−2x2−4 Solution 6(x+2)2−2(x+2)(x−2)Factor.6(x+2)2⋅x−2x−2−2(x+2)(x−2)⋅x+2x+2Multiply each fraction to get LCD as denominator.6(x−2)(x...
