化简(4+x)2-(4+x)(4-x)是(4+x)²-(4+x)(4-x)化简(4+x)2-(4+x)(4-x)是(4+x)²-(4+x)(4-x)化简(4+x)2-(4+x)(4
化简(4+x)2-(4+x)(4-x)是(4+x)²-(4+x)(4-x)
化简(4+x)2-(4+x)(4-x)
是(4+x)²-(4+x)(4-x)
化简(4+x)2-(4+x)(4-x)是(4+x)²-(4+x)(4-x)
(4+x)²-(4+x)(4-x)
原式=16+8x+x²-(16-x²)
=16+8x+x²-16+x²
=2x²+8x
(4+x)^2-(4+x)(4-x)
=16+8x+x^2-(16-x^2)
=2x^2+8x
(4+x)²-(4+x)(4-x)=(4+x)*[(4+x)-(4-x)]=(4+x)*[2x]=2x(4+x)
原式=(4+X)(2-4+X)
=(4+X)(X-2)
=X²+2X-8
