-4(pq+pr)+(4pq+pr)怎样化简-4(pq+pr)+(4pq+pr)怎样化简-4(pq+pr)+(4pq+pr)怎样化简-4(pq+pr)+(4pq+pr)原式=-4pq-4pr+4pq+
-4(pq+pr)+(4pq+pr)怎样化简
-4(pq+pr)+(4pq+pr)怎样化简
-4(pq+pr)+(4pq+pr)怎样化简
-4(pq+pr)+(4pq+pr)
原式=-4pq-4pr+4pq+pr
=(4pq-4pq)+(4pr-pr)
=0+3pr
=3pr
哈哈哈
原式=-4pq-4pr+4pq+pr=-3pr
等于-4pr-4pr+4pq+pr等于(4pq-4pq)+(4pr-pr)等于3pr
-4(pq+pr)+(4pq+pr)怎样化简
-4(pq+pr)+(4pq+pr)
-4(pq+pr)+(4pq+pr)
4(pq+pr)-(4pq+pr)+(rq-3pr) 化简
-4(pq+pr)+(4pd+pr)
-4(pq+pr)十(4pq+pr)=
-4(pq+pr)+(4pq+pr)
计算4(pq+pr)-(4pq+qr)+(rp-3pr)a.-3pr b.-2pr c.2pr d.pr
求-4{pq+pr}+{4pq+pr}的化简过程
─4(pq+pr)+(4pq+pr)的过程和值 急急急!给好评
化简哦,-4(pq+pr)+(4pq+pr) (2x-3y)-(5x-y)-4(pq+pr)+(4pq+pr)(2x-3y)-(5x-y)-5(x-2y+1)-3x+4y)
去括号:-2分之1(x+y)+4分之1(p+q) 化简:-4(pq+pr)+(4pq+pr)
先化简,再求值 4 (pq+pr)-(4pq+qr)+(rq-3pr),其中p=2/3,r=3/2
化简并求值:4(pq+pr)-(4pq+qr)+(rq-3pr) 其中p=5/2 r=2/3忘公式了
(1)-2n-(3n-1)(2)-3(2s-5)+6s(3)3(-ab+2a)-(3a-b)(4)3(xy-2z)+(-xy+3z)(5)-4(pq+pr)+(4pq+pr)今晚必须做完快,
简化代数式(包括去括号,合并同类项)(1)a-(5a-3b)+(2b-a)(2)14(abc-2a)+3(6a-2abc)(3)-4(pq+pr)+(4pq+pr)
-3(2s-5)+6s;1-(2a-1)-(3a+3);3(-ab+2a)-(3a-b); 14(abc-2a)+3(6a-2abc) ;-4(pq+pr)+(4pq+pr)
4(pq+pr)-(4pq+qr)+(rq-3pr)其中p=2分之5,r=3分之2谢谢,快
