4(2p+3q)^2-9(3p-q)^2 因式分解
4(2p+3q)^2-9(3p-q)^2 因式分解
4(2p+3q)^2 - 9(3p-q)^2
=[2(2p+3q) + 3(3p-q)][2(2p+3q) - 3(3p-q)]
=(4p+6q+9p-3q)(4p+6q-9p+3q)
=(13p+3q)(9q-5p)
4(2p+3q)^2-9(3p-q)^2
=(4p+6q-9p+3q)(4p+6q+9p-3q)
=(9q-5p)(10p+3q)
原式=[2(2p+3q)² -(3p+q)²]
=[2(2p+3q)+3p+q][2(2p+3q)-3p-q]
=(4p+6q+3q+p)(4p+6-3q-p)
=(5p+9q)(3p+3q)
=3(5p+9q)(p+q)
(p-q)^4/(q-p)^3*(p-q)^2 计算
计算:(p-q)^2 * (p-q)^3 * (q-p)^5
(p-q)^5/(q-p)^2·(p-q)^3
因式分解:(3p+2q)(3p-2q)(9p^2+4q^2)
(p-2q)^2-2(p+2q)(p+3q)+(p+3q)^2
因式分解(p+2q)^2-2(p+2q)(p+3q)+(p+3q)^2
4(2p+3q)^2 -(3p-q)^2
因式分解 P^2-4Q^2-3P+6Q
(3p+2q)乘以(p+4q)等于多少
因式分解(p+2q)^2-2(p+2q)(p+3q)+(p+3q)(3q-p)
p-[q+2p-( )]=3p-2q
(p+2q)(2p-q)-(p+q)(p-q)
6p(p+q)-4q(p+q)m(a-3)+2(3-a)
因式分解(2p+q)(8p-3q)-2p(2p+q)
先化简再求值:(p+2q)^2-2(p+2q)(p+3q)+(p+2q)(3q-p),其中p=-1,q=-2
将[(p-q)³-2(q-p)²-2/3(q-p)]/ p-q/3(p≠q)化归为关于p、q的多项式
因式分解p^3-p^2q-pq^2+q^3
计算:(p+2q-3)(p-2q+3)
