解説の真数は正であるから以降の X+1>0,x+2>0,2x+8>0 となる理由はなんですか?

別題 方程式 log2(x+1)+log2(x+2)=loga(2x+8) を解け。 9 左辺を log2M+log2N=log2MN を用いて変形する。 言え方 左辺を log2M+log2N=log2MN を用いて変形する。 真数は正であるから, x+1>0, x+2>0, 2x+8>0 解 これらを同時に満たすxの値の範囲は, x>-1 -4 -2-1 X 与えられた方程式を変形すると, log2(x+1)(x+2)%3Dlog2 (2x+8) logap=logaq 真数を比較して, p=q (x+1)(x+2)=2x+8 これを整理すると, x+x-6=0 これより, (x+3)(x-2)=0 x>-1 であるから, x=2

この証明は丸になるかどうか見ていただきたいです*_ _) (急いで書いたのですごい簡略化して、対応する点の順にかけてないと思います💦)
