Question

Can you help me again please
( Complete solution )​

Answer 1

Explanation:

x^2 +4x +4 => (x+2)^2

x^2 -8x +16 => (x+4)^2

4x^2 +12xy +9y^2 => (2x+3y)^2

x^4 -2x^2 +1 => (x^2-1)^2

Answer 2

#1

`\\ \sf\longmapsto (x+2)^2`

`\\ \sf\longmapsto x^2+4x+4`

#2

`\\ \sf\longmapsto (x-4)^2`

`\\ \sf\longmapsto x^2-8x+16`

#3

`\\ \sf\longmapsto (2x+3y)^2`

`\\ \sf\longmapsto 4x^2+12xy+9y^2`

#4

`\\ \sf\longmapsto (x^2-1)^2`

`\\ \sf\longmapsto x^4-2x^2+1`
