I need help with Algebra (Factoring Trinomials)?

OK, I really need an easy way to do this, because I'm very confused on how it's suppose to work.

One math problem

4b^2 - 22b + 10

now i have the answer, I'm just confused as to how to get it.

2(2b - 1)(b - 5)

I need help big time, because I have been working on this homework for 2 days now and it's on 19 problems and I'm still not getting it. Someone please help me.

firstly you take out the common factor of all three terms (the thing that divides by a aspects of equation) - in this case it is 2. so divide everything by 2 to get 2(2b^2-11b+5).

next you leave the 2 that you have already factored out and focus on the 2b^2-11b+5.

you factorises this to get (2b-1)(b-5)

finally you put the 2 back at the front of the equation to get 2(2b-1)(b-5)

hope this helps :)

1.) Find the greatest common factor.

-which would be 2.

2.)Divide everything by 2


3.)Factor out (2b-11b+5)

-you have to guess a little.

-then you get

(2b+1) (1-5)

4.)Just place the 2 in front of that and your done.
