(3x+1)²(3x-1)²
=(9x²-1)²
=81x的4次幂 - 18x² +1
.
x(x-5)²-x(x-5)(x+5)
=x(x-5)(x-5-x-5)
=-10x(x-5)
=(9x²-1)²
=81x的4次幂 - 18x² +1
.
x(x-5)²-x(x-5)(x+5)
=x(x-5)(x-5-x-5)
=-10x(x-5)

(3x+1)²(3x-1)²
=(3x+1)(3x+1)(3x-1)(3x-1)
=(3x+1)(3x-1)X(3x+1)(3x-1)
=(9x²-1)X(9x²-1)
=(9x²-1)²
=81x^4-18x² +1
x(x-5)²-x(x-5)(x+5)
=x(x-5)(x-5)-x(x-5)(x+5)
=x(x-5)(x-5-x-5)
=-10x(x-5)
=(3x+1)(3x+1)(3x-1)(3x-1)
=(3x+1)(3x-1)X(3x+1)(3x-1)
=(9x²-1)X(9x²-1)
=(9x²-1)²
=81x^4-18x² +1
x(x-5)²-x(x-5)(x+5)
=x(x-5)(x-5)-x(x-5)(x+5)
=x(x-5)(x-5-x-5)
=-10x(x-5)
