Subtraction: _____2x____ - ___7___ x^2-13x+42 x-6 3. Find LCD: _____7_____, ___8___ a^2+2a-63 a+9 4. Perform the indicated operation. Simplify if possible. ___6a^2-8a-8___ / ___a-2___ 2a^2-9a-56 a-8 Thanks! This question is from textbook introductory algebra Answer by stanbon(57250)   (Show Source): You can put this solution on YOUR website!1. How do I perform the indicated operation? 3 5 ___ - ___ 2b 3b^3 --------- lcd = 6b^3 Rewrite each fraction with the lcd as its denominator: ---------- = 9b^2/lcd - 10/lcd ------------ Combine the numerators to get: = [9b^2-10]/6b^3 ======================= 2. Subtraction: _____2x____ - ___7___ x^2-13x+42 x-6 ---------- lcd = (x-6)(x-7) Rewrite: [2x/lcd] - [7(x-7)/lcd] --------- Combine: = [2x-7x+49]/lcd = [-5x+49]/[x^2-13x+42] ============= 3. Find LCD: _____7_____, ___8___ a^2+2a-63 a+9 --------------- Rewrite: 7/[(a+9)(a-7)], 8/(a+9) ------------ LCD = (a+9)(a-7) =================== 4. Perform the indicated operation. Simplify if possible. ___6a^2-8a-8___ / ___a-2___ 2a^2-9a-56 a-8 --------- Factor where you can to get: [2(a-2)(3a+2)/(a-8)(2a+7)] Cancel where you can to get: =[2(3a+2)/(2a+7)] =================== Cheers, Stan H.
