factor each of the following:
a)x^2+10x+25
b)x^2+16x+28
c)x^29x+14

x^2+10x+25=(x+5)*(x5)
Becouse:
(x+5)*(x5)=x*x+5*x5*x25=x^2+5x5x+25=x^2+25
x^2+16x+28=(x+2)*(x+14)
Becouse:
(x+2)*(x+14)=x*x+2*x+14x+28=x^2+2x+14x+28=x^2+16x+28
x^29x+14=(x7)*(x2)
Becouse:
(x7)*(x2)=x*x7x2x+2*7=x^29x+14 
i don't realy get it still like i do get it but at the same time i don't :( sorry im being an thik head lol
