Best ResponseYou've already chosen the best response.0take a 2 out first. 2*(3x^2  2x  1)

Best ResponseYou've already chosen the best response.0okay i did that, then i did 2(3x3x)(x1)

Best ResponseYou've already chosen the best response.0you have factors 3 1  1 1 you need to make a 2 out of that , so +3 and 1

Best ResponseYou've already chosen the best response.0explain i dont get it

Best ResponseYou've already chosen the best response.0Here you can put in the x terms since 3 and 1 are the only choice 2*(3x )*(x )

Best ResponseYou've already chosen the best response.0and the other choice is only 1 and 1 for the others, you just have to decide the sign in each one + or

Best ResponseYou've already chosen the best response.0put in the + or  , so that when you distribute that, you get a 2 on the X term

Best ResponseYou've already chosen the best response.0i already put the x terms in as 2(3x3x)(x1)

Best ResponseYou've already chosen the best response.02*(3x^2  2x  1) = 2( 3x^2  3x + x  1) now factor the expression in the parentheses by grouping

Best ResponseYou've already chosen the best response.0first factor 3x^2  3x  take 3x out

Best ResponseYou've already chosen the best response.0no we are not solving an equation 3x^2  3x = 3x(x  1) do you get that?

Best ResponseYou've already chosen the best response.03x is the highest common factor of 3x^2 and 3x

Best ResponseYou've already chosen the best response.0oh so its not 2(3x^23x) + (x1)

Best ResponseYou've already chosen the best response.0well thats on the way to solving it but we need to factor the first 2 terms first  the 3x^2  3x

Best ResponseYou've already chosen the best response.02(3x^23x) + (x1) = 2 ( 3x( x  1) + 1(x  1) ) now as (x  1) is common to the 2 parts = 2 (3x + 1)(x  1)

Best ResponseYou've already chosen the best response.0 thats whats called factoring by grouping  grouping the first 2 terms and the last 2

Best ResponseYou've already chosen the best response.0wait so what happened to the 3x^2

welshfella

Best ResponseYou've already chosen the best response.0its was split into 3x and x 3x(x  1)

Best ResponseYou've already chosen the best response.0 that called factroing

Best ResponseYou've already chosen the best response.0oh so its still 3x^2. so why did you multiply x1 on both sides

welshfella

Best ResponseYou've already chosen the best response.0because (x  1) is common to both parts : 3x( x  1) + 1(x  1)

welshfella

Best ResponseYou've already chosen the best response.0well its like Ax  A b  you can take A out and the factors are A ( x  b) if A had been (x  1) we would take (x  1) out in a similar way

Best ResponseYou've already chosen the best response.0do you see the pattern there?

Best ResponseYou've already chosen the best response.0no that was an example of factoring b is just b i could have put any letter i liked there

Best ResponseYou've already chosen the best response.0i was illustrating how you can take out common items for an expression in order to factor them What goes in the brackets is what is left after taking out the common item.

Best ResponseYou've already chosen the best response.0* from an expression

Best ResponseYou've already chosen the best response.0oh okay so the final result is 2(3x+1)(x1)

anonymous

Best ResponseYou've already chosen the best response.0oh okay i got how you got 2(3x+1)(x1)

Best ResponseYou've already chosen the best response.0no there's no  there the 3 parts multiply each other its 2(2x +1(x  1)
