Answer 1

I can do this

Answer 2

so here's what I did...
(7x^2y^3 + 5x^3y^2 - 3y^3) - (-6x^3y^2 - 4x2^y^3 + y^3)
Being that there are two negatives we would do -6x^3y^2 x -1, -4x2^y3 x -1, and y^3 x -1? right? >~<

Answer 3

I’ll send you a pic when I solve this

Answer 4

okie dokie, I messed up somewhere though o.o

Answer 5

I got 11x^2y^3 + 11x^3y^2 - 4y^3

Answer 6

How

Answer 7

(7x^2y^3 + 5x^3y^2 - 3y^3) - (-6x^3y^2 - 4x^2y^3 + y^3)
I multiplied (-6x^3y^2 - 4x^2y^3 + y^3) = (6x^3y^2 + 4x^2y^3 -y^3). Then I combined de like terms and added. 7x^2y^3 + 4x^2y^3 = 11x^2y^3. 5x^3y^2 + 6x^3y^2 = 11x^3y^2. And -3y^3 + -y^3 = -4y^3. Then I connected them all together and got 11x^2y^3 + 11x^3y^2 - 4y^3.

Answer 8

Do you get how I did it?

Answer 9

nu

Answer 10

Damn

Answer 11

._. how did you get the first part: 3x^2y^3

Answer 12

I’m soooo sorry
I’m a horrible teacher

Answer 13

no no its fine haha

Answer 14

I’m sorry 😢😭

Answer 15

don't be, at least you tried ^_^!

Answer 16

😭😭😭

Answer 17

So do you understand that a - (-b) = a + b

Answer 18

Like let's start with the basics

Answer 19

And then just pay attention to the units. You can't add apples and oranges.

so like x^2y^3 make that an orange and just add all the oranges
x^3y^2 is an apple
and y^3 is a banana

like don't get confused between the exponents

Answer 20

Wait, I do 7x^2y^3 + 4x^2y^3 + -y^3 >~<?

Answer 21

Yes, but you dropped a lot of the other numbers but that 7 and 4 both have oranges!! o; which means you can add them

That y^3 is a banana and banana and oranges definitely don't add

Answer 22

I've honestly never taught it this way like using oranges and banana that it makes me sound really crazy but whatever helps you get the point to not add the wrong stuff together

Answer 23

Ah okie ouo so 7x^2y^3 + 4x^2y^3? And nu I like the idea

Answer 24

¯\_(ツ)_/¯
