256 + 112 - 24 =
344
Incorrect as 344 ≠ 0

Q(1) =

Factor by using the perfect-square trinomial formula. 100x^2+20x+1

a_sh-v [17]

To factor first multily 100 and 1 and get 100

then find what 2 numbers multiply to get 100 and add to get 20

the numbers are 10 and 10

so
split the center term up
100x^2+10x+10x+1
group
(100x^2+10x)+(10x+1)
undistribute
(10x)(10x+1)+(1)(10x+1)
undistribute/reverse distributive property
(10x+1)(10x+1)
(10x+1)^2
