Question

Help me with this question :


`\quad \tt \:( {a}^{} + b) {}^(2) =`
​

Answer 1

`{(a + b)}^(2)`

`(a + b)(a + b)`

`a ·a + a ·b + b ·a + b ·b`

`{a}^(2) + 2ab + {b}^(2)`

Step-by-step explanation:

`\frak{seolle_(aphrodite)}`

Answer 2

a² + 2ab + b²

Step-by-step explanation:

⇒ (a + b)²

⇒ (a + b)(a + b)

[apply distributive method: (a + b) (c + d) = ac + ad + bc + bd]

⇒ a² + ab + ab + b²

⇒ a² + 2ab + b²
