Question

Simplify 2a(b + a) - 2b(b - a)

Answer 1

`4ab + 2 {a}^(2) - 2 {b}^(2)`

Explanation:

`2a(b + a) - 2b(b - a)`

Expand by distributing terms:

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

Remove parentheses:

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

Collect like terms:

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

Simplify:

`4ab + 2 {a}^(2) - 2 {b}^(2)`

Hope this helps...

Good luck on your assignment...
