Question

Which diagram shows the X method being used correctly to factor the trinomial 2x2 – 3x + 1?

Answer 1

the answer is the 3rd one (it should be 2 on top, -2 on the left,-1 on the right,and -3 on the bottom.

Answer 2

Factoring trinomial is a little bit easy, you should know how to factor numbers. 

So let’s start

2x^2 – 3x +1 

The factors are (2x-1) and (x – 1)

Just get the 2nd constant which is -3 and put it in the top of the X.

Next just multiply the first and third constant on the given equation so you will get 2 then put it in the bottom of the X.

Get the factor of 2 it is only one which is 2 and 1 then by knowing the sign look at the 2nd term of the given equation and it is negative 3 so you will come up with the answer -2 and -1.
