4x^2+1/4-2x-9y^2因式分解
4x^2+1/4-2x-9y^2
因式分解
4x^2+1/4-2x-9y^2因式分解
4x^2+1/4-2x-9y^2=4(x^2-1/2x+1/16)-9y^2=4(x-1/4)^2-9y^2=(2x+3y-1/2)(2x-3y-1/2)
4x^2-2x+1/4-9y^2
=(2x-1/2)^2-9y^2
=(2x+3y-1/2)(2x-3y-1/2)
=(2X-1/2)^2-9Y^2
=(2X-1/2+3Y)(2X-2/1-3Y)
上班好无聊啊,帮小妹妹做算数- -!
4x^2+1/4-2x-9y^2
=4(x-1/4)^2-9y^2
=(2x+3y-1/2)(2x-3y-1/2)
4x^2+1/4-2x-9y^2
=4(x^2-1/2*x+1/16)-9y^2
=4(x-1/4)^2-9y^2
=[2(x-1/4)-3y][2(x-1/4)+3y]
4x(y-x)-y^2因式分解
因式分解:4x(y-x)-y^2
把4(x-y+1)+y(y-2x)因式分解
y(y+2)+4x(x-y-1)因式分解是多少
因式分解x^6-x^2y^4
4(x-y)^2-9(x+y)^2因式分解,
4(x+y)^2-9(x-y)^2因式分解,
因式分解9(x+y)^2-4(x-y)^2
4(x+y)^2-9(x-y)^2因式分解
因式分解:4(x+y)^2-9(x-y)^2
4(x-y)2-4x+4y+1因式分解
4-12(x-y)+9(x-y)^2 因式分解
4-12(x-y)+9(x-y)^2因式分解
9(x-y)^2+12(x-y)+4因式分解
4+12(x-y)+9(x-y)^2用因式分解
4(x+y)^2-12(x+y)+9因式分解
9-12(x+y)+4(x+y)^2因式分解
因式分解:4+12(x-y)+9(x-y)^2
