Back in 80s I was just trying get through high school, now my phone and youtube has help me get through college, and now I'm in my late 50s, with your help to pass my algebra class that I will be taking in 6 months prepared😊

[tshepomotau]

I have learned a new technique which I will also teach my students. Thank you so much.

[robertarguello]

There's nothing better during an exam, than to have a procedure that is "bulletproof". Thank you!

I'm 12 and a 7th-grade algebra student named Francisca, and I finally understand this!!!

[KirstinMarlyce]

I'm a mature student trying to cobble together some foundational knowledge and got myself into the weeds with factoring polynomials. This was my Thank you so much!!

[paytondaly]

This helped me learn more! I am gonna dive into your videos more. I am terrible at math. It is literally like greek to me. I am in a college math and its online so its teach yourself in a way. I love this video. Thank you!!

[nikolaristic]

I am a high schooler and have never been properly taught factoring of trinomials. Thank you!

[JuanCongosto-iyus]

You put more effort advertising your other videos than effectively explaining how to factor trinomials.

Love you bro I’m like staying up doing this math work

Greetings. Factoring the expression gives (2X+1)(3X-4). I usually concern myself with the middle term. In this case (2X)( -4) gives -8X, now we need to add +3X to get the result of -5X. Therefore (2X) should go in the first sets of brackets and -4 in the second sets of brackets. For our positive 3X we need to multiply 1 times 3X. These are our factors that must be placed in the different sets of brackets. Finally, we will group 2X +1 and 3X -4. Let us check, 2X times 3X =6X^2, 2X times minus 4= minus 8X, 3X times 1= positive 3X, minus 4 times positive 1 = Minus 4 and the result is 6X^ +(-8X +3X) -4 = 6X^2 -5X -4.

you got me subscribed with this one chief

cheers John. bought you course and love it. im 40 and going back to school. took the tsi and got a 957. I need a 960+ but I could tell just by doing the exam, the areas was weak in and in some cases didn't have clue. taking it again on Wednesday, fingers crossed

I'm 40 and helping my daughter...after how many years, this finally makes sense!

[SalvatoreIadicicco]

So Im struggling with how to figure out which number to put first. Other tutorials have put the larger number of the factor/sum AbC chart first and it completely changes the answer

[JamesS-C]

I was hoping you would have also shown the quadratic formula in this video.

[markmcgee]

GOOD! Just found a new manner of doing this.

[RespecttheFallen]

Great vid wish I didnt give up on math years ago and found this instead; So I wouldnt dive into Calc and fail it easily 😬

[aryusure]

I will close shop for the day leaving while I'm ahead because I got this one right, thanks to the best factoring hack. :)

This vid helps reinforce Yesterday's. TYSM

now that ive more of these its getting easier as a refresh (3x-4)(x+1) and so if you factor like this and is equals to 0 its x=4/3 and x= -1
