分解因式25x的2次方减16y的2次方-搜答案-智慧作业帮

7x^2-63=7(x^2-9)=7(x+3)(x-3)4x^2-16=4(x^2-4)=4(x+2)(x-2)(2x+1)^2-x^2=4x^2+4x+1-x^2=3x^2+4x+1=(3x+1)(

3（x-y）-2（x-y）²＝﹙x－y﹚﹙3－2x＋3y﹚.

答：-x³y+2x²y-xy=-xy(x²-2x+1)=-xy(x-1)²

X的4次方减18X的2次方加81=(x²-9)²=(x+3)²(x-3)²

x^6-y^6-2x³+1=x^6-2x³+1-y^6=(x^6-2x³+1)-y^6=(x³-1)²-(y³)²=(x³

3x的4次方+x的平方y-2y的平方=(x²+y)(3x²-2y)很高兴为您解答,【the1900】团队为您答题.请点击下面的【选为满意回答】按钮,再问：有过程吗，如果是一步的话有

1、（x-2）（x+3）-（x+3）²=(x+3[x-2-(x+3)²]=(x+3)(x-2-x²-6x-9)=(x+3)(-x²-5x-11)=-(x+3)(

x的4次方+2x平方-8=x的4次方+2x平方+1-1-8=(x平方+1)平方-9=(x平方+1+3)(x平方+1-3)=(x平方+4)(x平方-2)=(x平方+4)(x-√2)(x+√2)

25(x-2y)³+4(2y-x)=(x-2y)[25(x-2y)²-4]=(x-2y)[5(x-2y)+2)][5(x-2y)-2]=(x-2y)(5x-10y+2)(5x-10

x³y²－x的5次方=x³(y²-x²)=x³(y+x)(y-x)不懂的欢迎追问.再问：嗯，3Q顺便再问2个吧、、、8（x²-2y

3x的3次方-12x的平方y+12xy的2次方=3x(x^2-4xy+4y^2)=3x(x-2y)^2

答：x的3次方-x的2次方y-3x+3y=x³-x²y-3x+3y=(x-y)x²-3(x-y)=(x-y)(x²-3)=(x-y)(x-√3)(x+√3)

x^3-y^3=(x-y)(x^2+y^2+xy)

原式=(4x^2)^2-72x^2y^2+(9y^2)^2=(4x^2-9y^2)^2=(2x+3y)^2*(2x-3y)^2

X的4次方-3x平方+2=(x²-1）(x²-2）=（x-1)(x+1)(x-√2）(x+√2)

(x-y)的3次方-2a(y-x)的平方=(x-y)的3次方-2a(x-y)的平方=(x-y)的平方*(x-y-2a)再问：只能分解到这了吗

=(x^2-4)^2-y^2=(x^2-4+y)(x^2-4-y)

-24x^2y-12xy^2+28y^3解,得：==-4y(6x^2+3xy-7y^2)分解因式(x-y)²-(y-x)也是因式分解,解,得：==(x-y)^2+(x-y)==(x-y)[(

[(x-y)x]6+[(y-x)y]6=(x-y)6x6+(y-x)6y6=(x-y)6(x6+y6)=(x-y)6[(x2)3+(y2)3]=(x-y)6(x2+y2)(x4-x2y2+y4)欢迎来

x^4-8x^2y^2+16y^4=(x^2-4y^2)^2=(x+2y)^2(x-2y)^2
