因式分解: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原式=(4p+6q)^2-(9p-3q)^2=(4

因式分解: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
原式=(4p+6q)^2-(9p-3q)^2=(4p+6q+9p-3q)(4p+6q-9p+3q)=(13p+3q)(9q-5p)

上式=[2(2p+3p)+3(3p-q)][2(2p+3p)-3(3p-q)]

(9q-5p)(13p+3q)
