Square of a Trinomial

The square of a trinomial consists of: Example: ( 3x + 4y + 5z) ^2
square of each term, 9x^2 + 16y^2 + 25z^2
twice the product of the first and the second terms, 2(3x)(4y) = 24xy
twice the product of the first and the third terms, 2(3x)(5z) = 30xz
twice the product of the second and the third terms 2(4y)(5z) = 40yz
Answer: ( 3x + 4y + 5z) ^2 = 9x^2 + 16y^2 + 25z^2 + 24xy + 30xz + 40yz

Just use this method, it's easier if you use this.
1.) Square the 1st term.
2.)Square the 2nd term.
3.) Square the 3rd term.
4.) Multiply 1st and 2nd term and multiply the answer by 2.
5.)Multiply 1st and 3rd term and multiply the answer by 2.
6.)Multiply 2nd and 3rd term and multiply the answer by 2.

''this is so easy''
gets nosebleed
okay it was freaking hard

I have learned in this video that in order to solve the Square of a Trinomial, first, square all the terms, then twice the product of the first term and the second term, next, twice the product of the first and the last term, finally twice the product of the second and the last term. Thanks a lot Sir for making this video.

I learned so much in this video and now i know how to solve the square of a trinomial!

[jhoannaubatay]

I have learned in this tutorial video that first you must square the first, second and third term then twice the product of first and second term,  twice the product of first and third term and lastly twice the product of second and third term. Thank you sir!

[sharmaineoropasague]

The pattern's awesome!
I learned that, to square a trinomial, is just square all the terms, twice the product of the first and the second term, twice the product of the first and the third term, twice the product of the second and the third term!

The things that I have learned in this video are that the square of a trinomial consists of the square of the first, second and last term, twice the product of the first and the second term, twice the product of the first and the third term, then lastly, twice the product of the second and the third term. Thank you for this tutorial video, Sir Escol!

I have learned in this video how to get the Square of a Trinomial. Thanks for the video!

[wintergarden]

I have learned in this tutorial that the square of a trinomial consists of: square of the first, second and third terms; twice the product of the first and second terms; twice the product of the first and third terms; and twice the product of the second and the third terms. Thanks for the video, Sir!!

[euleanorgabriellecalibo]

In this video i learned that to get the Square of a trinomial, you have to square each term, then twice the product of the first and the second term;next twice the product of the first and the third term, finally twice the product of the second and the third term .Thanks to this video, i learned so much .it helped a lot in my studies.

I have learned in this video that the square of a Trinomial is just the square of the first term, the square of the second term, the square of the third term, twice the product of the first and the second terms, twice the product of the first and the third terms, and twice the product of the second and the third terms.

[fulgentlavesores]

I learned that in SOAT, we need to just square all the terms, twice the product of the first and the second term, twice the product of the first and the third term, twice the product of the second and the third term...Thanks a lot to this video sir!

Thanks a lot Sir for this video.

[alliahbalan]

I've learned about this video on how to solve square of a trinomial, first square each term, then twice the product of the 1st and the 2nd term, twice the prouct of the 1st and the 3rd term, twice the product of the 2nd and the 3rd term. Thanks for making this video sir!

[blessiefaithg.aldema]

I have learned in this video that  Square of Trinomial consists of sqaure of the first, second, and the third term.Then twice the product of the first and second term and twice the product of the first and third terms and lastly twice the product of the second and third term.This video tutorial is a great help for students that have difficulties in answering or solving.
