数学 高校生 2年以上前 数学の平方根の問題です 黄色のペンの部分がどうしてそうなるのかが分かりません。教えていただきたいです! よろしくお願いします🙇 (2) -1≦x<1のとき √√√x²+2x+1=√√√x²–2x+1= = 解説 (1) √(x-1)² = |x-1| x≧1のとき, |x-1|=x-1であるから √(x-1)² = =x-1 x<1のとき, |x-1|=-(x-1) であるから √(x−1)² = −(x-1)=−x+1 √√√x²+2x+1-√√√x²–2x+1=√√(x+1)² -√√(x-1)² = |x+1|-|x-1| -1≦x<1のとき, |x+1|=x+1, |x-1|=-(x-1) であるから √√x²+2x+1-√√√x² −2x+1=(x+1) + (x − 1) = 2x 回答募集中 回答数: 0
