Question

Simplify the expression :

3x² + 9x + 10²+ 5y +(-11x)

Answer 1

I cant help you! So do you know where we can start?

Answer 2

What do you mean?

Answer 3

Where do you think we should begin with this problem?

Answer 4

I don't know....It's been so long since I solved these kind of questions. I was hoping to get help from here to remind me.

Answer 5

Okay! Well let's start with 10^2. 10^2 means 10x10 which is?

Answer 6

100

Answer 7

Perfect! So we now have:

3x² + 9x + 100+ 5y +(-11x)

Let's group the common variables together. The only common variable is x, so:

3x² + 100 + 5y + 9x - 11x

Answer 8

What's 9x-11x?

Answer 9

-2

Answer 10

Close! We can't forget the 2x. 9x - 11x = -2x

So that gives us:

3x² +100 + 5y - 2x

Which is our final answer.

Answer 11

the answer choices are

a) 13x²+ 2x - 5y

b)13x² - 2x + 5y

c)11x² + 5y

d)15x² + 5y

Answer 12

Did you make a mistake in the original question?

You put: 3x² + 9x + 10²+ 5y +(-11x)

Answer 13

I think it's supposed to be: 3x² + 9x + 10x²+ 5y +(-11x) which would make the answer b

Answer 14

oh my!!! I'm sorry!

Answer 15

How would I solve the question to get B as my answer?

Answer 16

Same approach! Put the common variables and add them together. What are our two common variables?

3x² + 9x + 10x²+ 5y +(-11x)

Answer 17

As said by @alexrobin13 you would first need to combine like terms...

It seems as though you forgot x with `10^2` so lets make it as `10x^2`....so now we can combine like terms....

\(\huge{(3x^{2}+10x^{2})+(9x+(-11x))+5y}\)

Answer 18

13x² + 9x + (-11x) + 5y ?
