its a revision from last year's math (new quad)

Square root the first and last terms I think.

So 5x + 40xy + 4y.

ok

I'm not sure

I'm still in Al2

i'll try that

ya

You have to do something to the 40xy

I just don't know what

How to recognize a perfect square trinomial:

• It has three terms

• Two of its terms are perfect squares themselves

• The remaining term is twice the product of the square roots of the other two terms

(5x + 4y)^2

right i'm remembering everything now

Apparently this is how they teach 4th graders to do multiplication now

F

That makes no sense to me

What the heck

I know right..I am in calc1 atm and I can't decipher any of that....whatever happened to 0-9 on the top and side

Yeah I have no clue how that works...When I have kids im homeschooling them

Cause that's ridiculous

what... what *is* that???

it looks like the squares in science for genetics or whatever they're called

Punnett squares

My question is how did they gt 414 out of that

23 x 18

my question is how did they get anything out of that

But what happened to just memorizing a multiplication table

It hurts my brain

I had to do that

And it helped me

i had to do that too

like... the one thing thats helpful in math

I had to memorize the periodic table

It was awful

bruh-

i had to memorize some of the element symbols or whatever but not the whole table

oh wait- nvm it's coming back to me

Bruh they can't multiple straight so they did it diagonal

0 3 11 4

But the number inside the boxes don't make sense

Ok I found a video that explains the multiplication method
