なぜx²で割るのですか？ そういうもんなのですか？

例 1 方程式 Ttxtのおき換えを利用して、xの4次方程式 x **** を解け 2x-9x-x-9x+2=0 考え方 係数が中央の頃から左右対称である方程式を相反方程式という (日本医大) 解答 Focus この方程式は有理数係数では1次の因数をもたないので、代入して0になる有理数に 見つからない.つまり,因数定理は利用できない (ただし、奇数次の相反方程式はx+1 を因数にもつ.) x=0 は,明らかに解ではないので x=0 したがって, 方程式の両辺を”で割ると. 2x2-9x-1- + =0 x 2(x+1/21)(x+1)- 9 2 X -1=0 ...... ① &g) I-z ( ここで,t=x+ t=x+2 とおくと、 x x+1=(x+1)-2x1=1-2 割り算では割る数 0でないことを確言 しておく. 0を代入す と、左辺) = 2, 12(右)=0 となり 成り立たない。 tの2次方程式とし 考えることができ x+y (2)=(x+y)²-2xy ①に代入して, 2(-2)-91-1-0 2t2-9t-5=0 (2t+1)(t-5)=0 5とし 2' 1 したがって、(2x+2/+1)(x+15)=0 の x+ x 2' 1 両辺に x2 を掛けて, (2x+2+x)(x+1-5x) = 0 よって, 2x2+x+2=0 または x+-=5 x -1±√15i 5±√21 x= 2 x2-5x+1=0 より,を解いてもよい 与式が1次の因 理数係数)をも 相反方程式ではt=x+1とおけ XC ことがわかる.

物理の速度の合成です。1枚目の写真の公式だと足し算なのに、2枚目の写真だと速度の合成は三平方で解いているのですが、1枚目の写真の公式はいつ使うんですか？

速度の合成 → v = v₁ + v₂ ... (3) 式の意味…合成速度(m/s) は、2つの速度v1 [m/s], [m/s]の和である。 この速度をとの合成速度といい, 合成速度を求めることを速度の合成 composite velocity composition of velo

Supporters of fox hunting say that it helps control fox populations. Many other people, however, say that the sport is cruel. This feeling ( 4 ) fox hunting in the United Kingdom in 2004. A kinder but similar sport that has become popular as far away as New York is called beagling. Beagling utilizes beagles* instead of foxhounds, the people taking part do not ride on horseback, and the dogs chase rabbits more often than foxes. The events rarely end in the catching of a rabbit, let alone the killing of one. ( 5 ), the game is over as soon as the rabbit disappears into a hole in the ground. Beagling participants range from the very young, who are simply attempting to learn to manage the dogs, to former fox hunters who are too old to ride horseback. They all enjoy dressing up in old English
