1. 8/(x+4) +1 = 5x/(x^2-2x-24)2. 2x(x+3) - x/(x+7) = (x^2-1)/(x^2+10x+21)Any one able to show me where to start after figuring out the LDC would be my hero for the day!The LDC for 1 is (x-6)(x+4) and far 2 it's (x+3)(x+7) correct?
First ones answer is x= 8 and -9...corret ??? but the other one I can get anywher with is at alk..I get this(2x)(x+7) - (x) (3+3) = (y^2 -1)then I get (2x^2 +14 x)(x-3x) = (y^2 -1) but then I keep getting zero on both side???? Help please!!!
2x(x+7)-x(x+3) = x²-1x(2x+14-x-3)=x²-111x=-1x=-1/11
