https://31investment.com/quadratic-equation-deformation/ このサイトでは、半分2乗引く と書いてあるんですが、私の持っている教科書には 半分の2乗たす と書いてあります。 どっちも同じこと言ってるんですか？

例題 「次の2次方程式を(ェ+m)?=n の形に変形して解きなさい。 55(x+m)°=n の形に変形して解く *の2次方程式を(+m)*=n の形に変形して解きなさい。 0- (1) +7.2+3=0 (2)) 3-4c-130 (ァ+m)=D£°+2mz+m' の右辺に着目すると, m'はxの係数2mの半分の2乗 方 になっている。2m=p とおくと, 右の式が得 られる。よって, 2'+ pe+q=0 の形の方程式 を(z+m)°=n の形に変形するには, 次のよ うにすればよい。 2 -半分 ī の 定数項を右辺に移項。 の係数の半分の2乗を両辺に加える。 デ+p==-g→++(金)--0+()一 (+ガー-の+(全) 2 2 + pe+ 2 ニー 2 2 2 (2 2+pエ+q=0 の形にするため, まず°の係数で両辺をわる。

左のa＋b＝-p、ab＝qはどうしてこのような式になるのですか？
