no dont know where to start

b.(x-5)(x-5) foil it
=(x*x)+(x*-5)+(-5*x)+(-5*-5)
= x^2+(-5x-5x)+(25)
= x^2-10x+25
you owrk backwards

Answer 11

Could you be more specific? We need two numbers.

Answer 12

Their product is 25 and their sum is -10. Do you see that -5(-5)=25 and -5+-5 =-10?

Answer 13

So we see that the two numbers are -5 and -5 and therefore the factors are (x-5)(x-5)

Answer 14

yes
