叔新旭3512a的三次方加一,怎么因式分解?
翟庾苑19155837117 ______ (a+1)(a^2+1-a)

叔新旭3512a3+1 因式分解如题 因式分解 a3(次方)+1 -
翟庾苑19155837117 ______[答案] a^3+1=(a+1)(a^2-a+1)

叔新旭3512a的12次方+a的9次方+a的6次方+a的3次方+1 因式分解 -
翟庾苑19155837117 ______ 3道呀 1和3重复的嘛 12x方-3y方=3(2x-y)(2x+y) 0.49p^2-144=(0.7p)-12^2=(0.7p-12)(0.7p+12) (2x+y)^2-(x+2y)^2=(2x+y+x+2y)(x+y-2x-y)=-3x(x+y)

叔新旭3512a的4次方+a的3次方+a+1 因式分解 -
翟庾苑19155837117 ______ a的4次方+a的3次方+a+1 = a^3(a +1) + (a +1) = (a + 1)(a^3 + 1) =(a + 1)(a + 1)(a² - a +1) = (a + 1)² (a² - a +1) 请采纳

叔新旭3512因式分解 a的三次方+a的平方+a+1 -
翟庾苑19155837117 ______[答案] a³+a²+a+1 =a²(a+1)+(a+1) =(a+1)(a²+1)

叔新旭3512a三次方 - 1 因式分解 -
翟庾苑19155837117 ______[答案] a³-1 =a³-1+(a²-a²)+(a-a) =(a³+a²+a)-(a²+a+1) =a(a²+a+1)-(a²+a+1) =(a-1)(a²+a+1) 拆添项法

叔新旭3512a的4次方+a的3次方+a+1怎么因式分解
翟庾苑19155837117 ______ a^3(a+1)+a+1=(a^3+1)(a+1)

叔新旭35122、若x的3次方+5的2次方+7x+a 有因式x+1,求a,并将原式因式分解麻烦写一下过程 -
翟庾苑19155837117 ______[答案] 应该是5X的两次方,否则此题目没有意义 =(x^3+x^2)+(4x^2+4x)+(3x+a) =x^2(x+1)+4x(x+1)+3(x+a/3) a=3 =(x+1)(x^2+4x+3) =(x+1)(x+3)(x+1) =(x+1)^2(x+3)

叔新旭35122x的三次方 - x+1因式分解 -
翟庾苑19155837117 ______[答案] 2x的三次方-x+1 =(x³-x)+(x³+1) =x(x²-1)+(x+1)(x²-x+1) =x(x+1)(x-1)+(x+1)(x²-x+1) =(x+1)(x²-x+x²-x+1) =(x+1)(2x²-2x+1)
