There is a factor of 2 common to all three terms, so take that out:



From there all you have to do is note that 10 plus 10 is 20 and 10 times 10 is 100 to find the two binomial factors of the quadratic trinomial.

factor 2 first
x^2+20x+100
find factors of 100 which add up to 20
10 and 10
2*(x+10)^2
