Question

Factor completely: 2x2 + 5x + 2

Prime

(2x + 2)(x + 1)

(2x − 2)(x − 1)

(2x + 1)(x + 2)

Answer 1

When you have choices, it's easy to just distribute them and see if any matches 2x2 + 5x + 2

Answer 2

Im not good with this lesson can you show mw how to do it ?

Answer 3

Alright, I'll do the first one:
(2x + 2)(x + 1) = 2x2 + 4x + 2
So it's not option 2

Answer 4

I don't get how to do it though

Answer 5

You can't answer this kind of questions if you don't know how to distribute. I'll try my best to explain. It works like this:
a*(b + c) = a*b + a*c
(a + b)(c + d) = ac + ad + bc + bd
Because + is distributive !
