Question

Find the product of (a + b + c) and (a + b)​

Answer 1

`a^2+b^2+2ab+ac+bc`

Explanation:

`(a+b+c(a+b)=\\a^2+ab+ac+ab+b^2+bc=\\a^2+b^2+ab+ab+ac+bc=\\a^2+b^2+2ab+ac+bc`

Answer 2

a² + 2ab + b² + ac + bc

Explanation:

(a + b + c) * (a + b) = aa + ab + ac + ba + bb + bc

= a² + 2ab + b² + ac + bc

The trick you use here is called the distributive property.
