yes, you are right,
For these kind of problems why don't you just expand your answer using FOIL to check if you are right?
Can someone check my answer please! I'm not sure this is right
x(squared)+7x+10=0
(x+r)(x+s)
=x(squared)+sx+rx+rs
=x(squared)+(r+s)x+rs
x(squared)+(r+s)x+rs=x(squared)+7x+10
r+s=7
rs=10
(2)(5)=10 and 3+4=7
x(squared)+7x+10=(x+5)(x+2)
