(2x-1)(2x+1)(4x*2+1)(16x*4+1) 怎么写这题?注意写过程.
(4x*2+1)(16x*4+1)是指
4x的平方+1乘以16x的四次方+1
(2x-1)(2x+1)(4x*2+1)(16x*4+1) 怎么写这题?注意写过程.(4x*2+1)(16x*4+1)是指4x的平方+1乘以16x的四次方+1
=(4x*2-1)(4x*2+1)(16x*4+1)
=(16x*4-1)(16x*4+1)
=256x*8-1
都是平方差公式,(2x-1)(2x+1)(4x*2+1)(16x*4+1) =(4x*2-1)(4x*2+1)(16x*4+1) =
(16x*4-1)(16x*4+1) =256x*8-1
