the polynomial is -10x(squared) + 11x - 3 The negative didn't make it hard, it made it easier because 2 negatives cancel each other out. I used F.O.I.L. method
Correct! Good reasoning.
The polynomial is -10x^2+11x-3. I used the box method.
-2x -10x^2 6x
+1 5x -3
then i combined like terms (6x+5x+11x) and wrote the new polynomial -10x^2+11x-3.
Correct! Good explanation even though the box is hard to show in the comments.
uggghhhhh it got messed up!!!!!
I'll stop screaming now
I used both methods, here is the foil method:
So, the simplified answer is -10x^2+11x-3
Question- So, I know that the algebra blocks were too confusing and we didn't use them, but during the PowerPoint, I had a question. When x, a bar was multiplied by another x, another bar, they created a square...makes sense. But, what if those x values were equal to one? One times one equals one, so the bar would stay a bar and not become a square...right?
Great explanation using FOIL.
Emily is correct that it would just make a square with side lengths of 1. The tiles just show x as a row because it represents some mystery side length we don't know, but it could be 1.
I get what you are saying Hazel. But when you multiply x by x, you get x^2, and it would create a square which would have sides equaling x. Try using the box to help. x times x equals x^2 , so 1 times 1 would equal 1^2 which would create a square with sides of 1. Did that help? Idk if i'm right but that is how I see your question.
I like this video . Also does it matter if u either to the table way or the F. O. I. L way ?
Nope, both ways give you the same answer.
I like your TMNT shirt!
Thanks! And your correct!
I played a monopoly game that kind of got out of hand. We started calmly like normal people, but in the end, people robbed the bank, threw game pieces across the room, and started a civil war over the remaining land.
i have a question mr bigsby. will we learn how to divide polynomials? it seems easy enough wouldn't you do the same thing as multiplication but instead of multiplying everything you would just divide it?
for example, (2x)= x=13
We are kind of dividing when we factor but direct dividing would use the distributive property.
(3x^2 + 15x + 6) / 3 =
Use distributive property
3x^2 / 3 = x^2
15x / 3 = 5x
6 / 3 = 2
x^2 + 5x + 6
I was kinda confused in class but that made it easier
Larry is real
Mr Bigsby is the best!
I needed extra credit so I asked a question late..
What if u cant find any solutions will u call it prime?
The box method is definitely my favorite
