x(a-b)*2n+y(b-a)*2n-1 怎么因式分解,
x(a-b)*2n+y(b-a)*2n-1 怎么因式分解,
x(a-b)*2n+y(b-a)*2n-1 怎么因式分解,
x(a-b)*2n+y(b-a)*2n-1
=(a-b)(2nx-(2n-1)y)
=(a-b)(2nx-2ny+y)
=(a-b)*2n)x-(a-b)(2n-1)y
=(a-b)[(2n)x-(2n-1)y]
(x+y+z)^2-(x-y-z)^2(a-b)^n+2 -(a-b)^n
x^2y(a-b)^2n+xy^2(b-a)^2n+1因式分解
分解因式:x(a-b)2n次方+y (b-a)2n+1次方
x(a-b)*2n+y(b-a)*2n-1 怎么因式分解,
x(a-b)的2n次方+y(b-a)的2n-1次方=?
因式分解:x(a-b)2n+y(b-a)2n+12n,2n+1是(a-b)和(b-a)的乘方
已知a,b,x,y都是实数,n∈N,x+yi=(a+bi)^n,求证:x^2+y^2=(a^2+b^2)^n
分解因式:x(a-b)^2n+y(b-a)^2n+1(n为正整数.)
(a^n+b^n)(a^2n-a^n*b^n+b^2n)
因式分解:a(x-y)的n次方-3b(y-x)的n+1次方+2c(y-x)的n+2次方(n为正整数)
A={y|y=x2-4x+6,y属于N},B={y|y=-x2-2x+18,y属于N},求A交B.
设函数y=(x^2-x+n)/(x^2+1),(n是正整数)的最小值为a(n),最大值为b(n),又c(n)=4a(n)b(n),求和:设函数y=(x^2-x+n)/(x^2+1),(n是正整数)的最小值为a(n),最大值为b(n),又c(n)=4*a(n)*b(n),求和:s(n)=1/c(1)*c(2)+1/c(2)*
因式分解;y^n-y^n-2 (n为正整数,且n大于2=多少因式分解;a^4x^n+2-4x^n (n为正整数)=多少因式分解;25a^n+2-10a^n+1+a^n=多少因式分解;a^2n+6a^nb^n+9b^2n=多少
(a-b)^n(b-a)^2n(a-b)^5
2(a-b)^2n*3x(b-a)^2n-2*4y(a-b)^3(n是正整数)
matlab利用递归求解差分方程function y = recur(a,b,n,x,x0,y0);%% y = recur(a,b,n,x,x0,y0)% solves for y[n] from:% y[n] + a1*y[n-1] + a2*y[n-2]...+ an*y[n-N]% = b0*x[n] + b1*x[n-1] + ...+ bm*x[n-M] %% a,b,n,x,x0 and y0 are vectors% a = [a1 a2
已知x+y=a+b x^3+y^3=a^3+b^3 求证x^2n+1+y^2n+1=a^2n+1+b^2n+1
分解因式x(a-b)的2n次方+y(b-a)的2n+1次方
