Question

Simplify the expression: (x + 3)(2x - 1)

Answer 1

use the distributive property and yet rid of the parenthesis (or however you spell that)
and get x+3×2x-1
then add like terms
and get
3x+2.
that's your answer.
3x+2

Answer 2

(x+3) (2x-1)

So first, you want to combine the x's. To do this, count the x in (x+3) as 1. So the x's combined are equal to 3x. Now, combine the 3 and -1. This expression simplified is equal to [ (3x+2) ]
