Answer: (x+10) to the seccond power
Step-by-step explanation: 1
Use the sum-product pattern
x^{2}+{\color{#c92786}{20x}}+100
x^{2}+{\color{#c92786}{10x}}+{\color{#c92786}{10x}}+100
2
Common factor from the two pairs
x^{2}+10x+10x+100
x(x+10)+10(x+10)
3
Rewrite in factored form
x(x+10)+10(x+10)
(x+10)(x+10)
4
Combine to a square
