問題の言ってる意味がよくわかりません、、💦 解き方教えてください、、💦

10 2次方程式の利用 学習2 >長さ 学習1 数の問題 >2次方程式を利用して文章題を解く手順 例題 1 どの数量を文字を使って表すかを決める。 直方 2 数量の間の関係を見つけて, 方程式をつくる。 3つくった方程式を解く。 解き 4 解が問題に適しているか確かめる。 >文字を使って数を表す。 3つの続いた整数…もっとも小さい数をcとすると, x, α+1, x+2 と表される。 題1 大小2つの整数がある。その差は6で, 積は91である。2つの整数を求めなさい。 解き方 小さいほうの整数をxとすると, 大きいほうの整数は x+6 と表される。 一手順D 2つの整数の積は91であるから (x+6)=91 2°+6.c-91=0 手順2 (x-7)(x+13)=0 したがって, x=7, x=-13 手順3 2=7 のとき, 大きいほうの整数は, 7+6=13 =-13 のとき,大きいほうの整数は, -13+6=-7 これらは問題に適している。 0=ト+( 手順4 圏7と13, -13と-7 1 2つの続いた自然数がある。それぞれを2乗した数の和が41になるとき, 次の問いに答えなさい。 問題 口(1) 2つの自然数のうち, 小さいほうの自然数をcとして, xについての方程式をつくりなさい。 1(2) (1)の方程式を解いて, この2つっの続いた自然数を求めなさい。 o1
