The following equation is what I'm working on 12x^3-28x^2+3x-7, I came up with the following answer 4x^2(x-7)(3x+7). Can someone tell me if I got it right, if not can you pls assist me?

OpenStudy (anonymous):

its not an equation

OpenStudy (anonymous):

technically thats an expression

OpenStudy (anonymous):

oh ok now I know for the future... thx.

OpenStudy (anonymous):

i mean... equations are supposed to have an = sign expressions do not and yes it looks good

OpenStudy (anonymous):

wait

OpenStudy (anonymous):

the first term

OpenStudy (anonymous):

you factored the 4 incorrectly

OpenStudy (anonymous):

Basically you are trying to factor by grouping. You have the following polynomial:\[\bf 12x^3-28x^2+3x-7\]Factor \(\bf 4x^2\) from first two terms:\[\bf 4x^2(3x-7)+3x-7\]We can re-write this as:\[\bf 4x^2(3x-7)+1(3x-7)\]Since both share (3x-7), we can factor it out and the final factored form becomes:\[\bf 12x^3-28x^2+3x-7=(4x^2+1)(3x-7)\]

i if i am not making any mistake i think that is it

OpenStudy (anonymous):

ehh you kinda just gave the answer @genius12

OpenStudy (anonymous):

btw how do you get that bold print ?

OpenStudy (anonymous):

@mth3v4 I showed him how to do it. Didn't just give the answer. From his answer I knew he was on the right track, showing him the rest of the way should probably fix his issues. @mth3v4 Type "bf" without the quotes in the equation editor before the rest of the expression/equation. "bf" stands for boldface.

suspects some super smart person to bonk me in the head*

OpenStudy (anonymous):

:P

Genius12 Thanks for the assistance I appreciate it. That does look like what I was missing, I just wasn't sure about mine and it didn't look right. Thx again. mth3v4 thank you too, for giving it a shot.
