15a(4)- 21a³= 3a³.(5a-7)
am-9an+5a= a.(m-9n+5)
5x+5y+ax+ay=5.(x+y)+a.(x+y)=(x+y).(5+a)
a³+3a²+2a+6=a².(a+3).2.(a+3)
81a²-x²y²(9a+xy)(9a-xy)
(p+10)²-100= (p+10-10).(p+10+10)=(p).(p+20)
(a+xy)²-x²y²=(a+xy-xy).(a+xy+xy)=(a).(a+2xy)
25y²+10xy+x²=5y x(5y+x)²
x²-2x+1x 1(x-1)²
25y²-10xy+x²=5y x(5y-x)²
3x²-27y²3.(x²-9y²)3.(x-3y).(x+3y)
