help me out 18a^2- …
help me out 18a^2-49b^2
n^3+5n^2-4n-20
Your explanations …
Your explanations are very clear.
Thanks for helping students across the globe , succeeding in algebra!
Great vid.
Directions: Pause …
Directions: Pause in the beginning and try to factor. Then, when you are done or get stuck, fast forward to 1:20 to the solution. Pause and try the next problem and then fast forward to 2:31 to see the solution and notice the next problem cannot be factored because it is not a difference.
thanks
thanks
if the polynomial …
if the polynomial cannot be factored, arent you suppose to write “prime”?
you can’t because …
you can’t because you can’t factorise a, since it’s already factorised from a squared to a
X^2 – 18 could be …
X^2 – 18 could be factored into (x + square root of 18) ( x – square root of 18), but we usually only look at rational answers, so we are looking for perfect squares, and 18 is not a perfect square. So in this case we would say. “can not be factored”
If you are refering …
If you are refering to the bracket (a – 4), it can NOT be factored even though the “4″ is a perfect square. The problem is that “a” is NOT a perfect square. Both have to be perfect squares.
I believe the first …
I believe the first equation can be factored more since 4 is a perfect square.
What happens when …
What happens when you have a number that cant divide equally like 18?
cheers, this helped …
cheers, this helped a lot
I assume you mean …
I assume you mean 2x^2 + 4. If so, then take out the common factor of 2 like this: 2 (x^2 + 2). After that it can NOT be factored over rational numbers.
how do u factor 2x^ …
how do u factor 2x^ + 4?
25p^2+81 is simpler …
25p^2+81 is simpler than (5p+9)^2, therefore is the same level factored because it has the same amount of exponents and plus/minus signs, but if you were taught to do that, I reccomend you please your teacher and do so, however it is the SAME thing.
u rock.
u rock.
you just helped me …
you just helped me through my homework and on my way to a good grade (a much needed one) thanks again!
THANK YOU SOOO MUCH …
THANK YOU SOOO MUCH. Subbed
I love those pens..

YOU ARE GOD!!!!!
YOU ARE GOD!!!!!
by the way, you …
by the way, you sound like Stephen King
You are amazing, I …
You are amazing, I love you
he meant “since”
he meant “since”
When you say it …
When you say it cannot be factored,
i was taught to do this>>>
25p^2+81
*(5p+9)(5p+9)
*(5p+9)^2
I only want a reply from the user,
PLEASE HELP ME, cause im confused and ive got a quiz thursday!!
sorry i rated4 …
sorry i rated4 stars when i meant to rate 5 stars sorry!!!!! but good job!!!!!!!
Great video mate!!! …
