Answer 1

(x + 3)(2x - 1)

2x^2 - x + 6x - 3

2x^2 + 5x - 3

Answer 2

`2x^2+5x-3`

Explanation:

`(x + 3)(2x- 1)`

Apply FOIL method to multiply the parenthesis

First we multiply x with 2x+1

`x(2x-1)= 2x^2 -x`

Now we multiply 3 with 2x-1

`3(2x-1)=6x-3`

`(x + 3)(2x- 1)`

`2x^2 -x+6x-3`

Combine like terms to simplify it

`2x^2+5x-3`
