(Section 0.9: Simplifying Algebraic Expressions) 0.9.7 We will multiply the numerator and the denominator by the Least Common Denominator (LCD), 34x+7()2/3, or 3u. =x+7±²³´2x4x+71/3µ4x2x+7±²¶¶³´··x+7±²³´4x+7±²³´or3u±²³´2xuµ4x23u±²¶³´·3u±²³´u±²³´WARNING 7:Do notcancel the expressions above in red. We must apply the Distributive Property. If it helps, write the following step; with experience, you can skip it. =x+7±²³´2x4x+7±²³´µ4x2±²¶¶³´··x+7±²³´4x+7±²³´
