help

Answer 1

well, what is x

Answer 2

taht would help

Answer 3

@AZ he's like mad smart but i can help you too if you want.....whoever you prefer also @snowflake0531

Answer 4

\( 4x^2 - 3x + 9 - (6x^2 +5x -9) \)

Can you distribute the - sign inside the parenthesis?

Basically the + inside will become -
and the - will become +

Answer 5

so 6x^2-5x+9?

Answer 6

yes but the 6x^2 would also get a minus in front of it since technically it's a positive number and we're distributing that negative sign inside, if that makes sense

if it was (-6x^2) inside then it would have become +6x^2

so now we have
\( 4x^2 - 3x + 9 - 6x^2 -5x +9\)

Answer 7

Do you know how to add like terms?

You can only add/subtract the terms that both have x^2 or x or are just a number

So for example, you cannot add/subtract 4x + 3 because 4x has an x and 3 does not

Answer 8

try doing this x2 + 4x - 9

Answer 9

would 7x^2 +9-11x^2+9 work for adding like terms

Answer 10

No no

let me add some colors
\( 4\color{red}{x^2} - 3\color{orange}{x} + 9 - 6\color{red}{x^2} -5\color{orange}{x} +9\)

Now let's simplify it one at a time

So what is \( 4x^2 - 6x^2 =\)

Answer 11

-2x^2

Answer 12

Good!

So now we have

\( -2x^2 - 3\color{orange}{x} + 9 -5\color{orange}{x} +9\)

now what is
\( -3x - 5x = \)

Answer 13

-8x

Answer 14

so -2x^2-8x+18

Answer 15

You got it!!

Answer 16

ok thank you your so smart

Answer 17

You're welcome!
