7𝑥^2 + 2√14𝑥 + 2

7𝑥^2 + 2√14𝑥 + 2

We can further write it as

= 7𝑥^2 + √2√7𝑥 + √2√7𝑥 + 2

By taking out the common terms

= √7𝑥(√7𝑥 + √2) + √2(√7𝑥 + √2)

So we get,

= (√7𝑥 + √2)(√7𝑥 + √2)

It can also be written as

= (√7𝑥 + √2)^2

7𝑥^2 + 2√14𝑥 + 2

7𝑥^2 + 2√14𝑥 + 2

We can further write it as

= 7𝑥^2 + √2√7𝑥 + √2√7𝑥 + 2

By taking out the common terms

= √7𝑥(√7𝑥 + √2) + √2(√7𝑥 + √2)

So we get,

= (√7𝑥 + √2)(√7𝑥 + √2)

It can also be written as
