计算:(x-2)^2(x+2)^2(x^2+4)^2计算:(9x^2-25y^2)÷(3x+5y)=?
计算:(x-2)^2(x+2)^2(x^2+4)^2
计算:(9x^2-25y^2)÷(3x+5y)=?
计算:(x-2)^2(x+2)^2(x^2+4)^2计算:(9x^2-25y^2)÷(3x+5y)=?
(x-2)^2(x+2)^2(x^2+4)^2
=(x^2-4)^2(x^2+4)^2
=(x^4-16)^2
=x^8-32x^4+256
(9x^2-25y^2)÷(3x+5y)=(3x+5y)(3x-5y)÷(3x+5y)=3x-5y
冤死=[(x-2)(x+2)(x^2+4)]^2
=[(x^2-4)(x^2+4)]^2
=(x^4-16)^2
=x^8-32x^4+256
原式=[(X-2)(X+2)]²(X²+4)²
=(X²-4)²(X²+4)²
=[(X²-4)(X²+4)]²
=(X^4-16)²
=X^8-32X^4+256
若有疑问可以百度Hi、
原式=(X^2-4)^2(X^+4)^2=X^4-16
(x-2)^2(x+2)^2(x^2+4)^2
=[ (x-2)(x+2)(x^2+4) ] ^2
=[(x^2-4)(x+4)^2]^2
=[x^4-16]^2
=x^8-32x^4+256
(x-2)^2(x+2)^2(x^2+4)^2=(X^2-4)^2(X^2+4)^2=(X^4-16)^2=X^8-32X^4+256
(9x^2-25y^2)÷(3x+5y)=(3X+5Y)(3X-5Y)/(3X+5Y)=3X-5Y
1、=(x^2-4)^2(x^2+4)^2=(x^4-16)^2
2、=(3x+5y)(3x-5y)/(3x+5y)=3x-5y
