【導(dǎo)讀】8.用秦九韶算法計(jì)算多項(xiàng)式f=x6-12x5+60x4-160x3+240x2-192x+64當(dāng)x=2時。9.用秦九韶算法計(jì)算多項(xiàng)式f=6x6+5x5+4x4+3x3+2x2+x+7在x=,11.用秦九韶算法求多項(xiàng)式f=12+35x-8x2+79x3+6x4+5x5+3x6在x=-4的值時,∴210與98的最大公約數(shù)為14.v2=-10×2+60=40,v3=40×2-160=-80,v5=80×2-192=-32,∴加法6次,乘法6次,10.D[將函數(shù)式化成如下形式,v1=1×3+0=3,v3=11×3+3=36,v4=36×3+1=109,解析v4=x+a2,把a(bǔ)6=3,a5=5,a4=6,a3=79,a2=-8,x. =-4代入可得v4=220.故168,54,264的最大公約數(shù)為6.v1=5×5+2=27,
