저의 첫 문제입니다. 많이 풀어주세요!

 

 

오차방정식의 근의 공식은 존재하지 않습니다.

하지만 우리는 인수분해를 해서 오차방정식을 풀 수 있습니다.

문제를 풀어 보세요!

(1) x4+3x2+4를 인수분해 하여라

 

(2) 방정식 x5-x4+x3-x2+x=1을 (x+a)(x4+bx3+cx2+dx+e)=0의 꼴로 나타내어라. (단, a,b,c,d,e는 실수)

 

(3) x4+bx3+cx2+dx+e를 인수분해 하여라

 

(4) 방정식 x5-x4+x3-x2+x=1의 다섯가지의 해를 모두 구하여라

 

이 문제 어떠셨나요?

글쎄요
