3y³-3y
2a³-8a
40b-10b³

Answer 1

5$x^{2}$-5=5($x^{2}$-1)=5*(х-1)(х+1)
2$а^{2}$-8=2($а^{2}$-4)=2(а-2)(а+2)
3а$n^{2}$-27a=3a($n^{2}$-9)=3f(n-3)(n+3)
2x$y^{2}$-50x=2x($y^{2}$-25)=2x(y-5)(y+5)
$x^{3}$-9x=x($x^{2}$-9)=x(x-3)(x+3)
3$y^{3}$-3y=3y($y^{2}$-1)=3y(y-1)(y+1)
2$a^{3}$-8a=2a($a^{2}$-4)=2a(a-2)(a+2)
40b-10$b^{3}$=10b(4-$b^{2}$)=10b(2-b)(2+b)
