=-(2m-n+p)(2m-n-p)
=-[(2m-n)+p][(2m-n)-p]
=-[(2m-n)²-p²]
=-(4m²-4mn+n²-p²)
=p²-4m²+4mn-n²
(—2m+n—p)(2m—n—p
=-[(2m-n)+p][(2m-n)-p]
=-[(2m-n)²-p²]
=-(4m²-4mn+n²-p²)
=-4m²+4mn-n²+p²
(m-2n-p)(m-2n+p)-(m+2n+p)(m+2n+p)
点P(m,n)是1110°角的终边上任意一点(m²—n²)/(m²+2mn+n²)=(m-n)(m+n)/(m+n)²=(m-n)/(m+n)
化简,1.[(m+n-p)(m+p+n)-(m+n)²]/(-p),2.[(m+n)(m-n)-(m-n)²+2n(m-n)]/4n
化简(-m+2n-p)(-p-2n+m)
(2m+n-p)(2m-n+p)
(2m+n-p)(2m-n-p)等于什么
(2m+n-p)( 2m+p-n)
(m-2n-p)(-m-2n-p)
化简:(2m+n-p)*(2m-n+p)
(-2m-3n-p)(2m-3n-p)
(m-2n+3p)(m+3n+3p)
因式分解:(m-n)(p-q)-(n-m)^2(q-p)
(—2m+n—p)(2m—n—p)急求啊~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~如果把负号提出来怎么算,急~~~~~~~~~~~~~~~~~
(2m+n-p)²
m-(2m-n-p)=
(m+n)-( )=2m-p
(m-n)(p-q)(p+2q)-(n-m)(p+q)(p+2q)
已知m、n、p为正实数,且m²+n²—p²=0,求p/(m+n)的最小值
