Operations with Polynomials: 4x2-x[6x-7 (2-3x2)-10x2]

[jsaunders94]

I am struggling with another problem and can't figure it out, 4x2-x[6x-7 (2-3x2)-10x2]

I am struggling with another problem and can't figure it out, 4x2-x[6x-7 (2-3x2)-10x2]

Is your polynomial expression:

4x²-x[6x-7 (2-3x²)-10x²]

which can be written as:

4x^2-x[6x-7 (2-3x^2)-10x^2] → Please correct your post.

What do you need to do with this expression? simplify?

Please share your work with us .

If you are stuck at the beginning tell us and we'll start with the definitions.

Hello J:

Please tell us whether you have learned about the Order of Operations. That is, do you know what it is?

Also, have you learned yet the Distributive Property?

I think that Subhotosh guessed correctly; the instruction is probably to simplify the given expression.

To do that, you need to understand the topics above.

Hint: Start within the inner-most grouping symbols, and work outwards.

Please, show us your effort (even if you think that its wrong).

Cheers :cool:

would I be substituiting the x first and multiplying the x times 6x?

would I be substituiting the x first

I do not understand the meaning of "substituting the x".

Volunteer tutors are trying to help you, but you are not paying attention.

You need to answer the questions asked by Subhotosh and Quaid.

You were also instructed to read the forum guidelines. (It seems like you did not do that, either.)

First: click HERE.

Second: Show us your initial effort(s). Then, maybe, we can determine what you you're trying to say about "substituting the x".

Thank you. :cool:

That is my intital effort but I am stuck so I really need help to solve this problem

First you need to fix your post!

As posted - it does not make sense!

It was hard tying this problem what meant to type is 4x to the square root of 2 minus x [6x-7(2-3x to the square root of 2) minus 10x to the square root of 2.

I showed you - how to correct your post:

If you wanted to write:

4x²-x[6x-7 (2-3x²)-10x²]

You should write

4x^2-x[6x-7 (2-3x^2)-10x^2] → Please correct your post.

Even this does NOT make sense:

4x to the square root of 2 minus x [6x-7(2-3x to the square root of 2) minus 10x

There is a HUGE DIFFERENCE between square and square-root

x² → x square → x to the POWER of 2 or x square

x to the (power of) square root of 2 → x^√2

Note: The most important point, in whatever formatting you use, is to be clear with your grouping symbols!

Hello jsaunders:

It appears that you need face-to-face tutoring. Please chat up your instructor, or talk to an adviser at your school. They can help you find a qualified tutor.

In the meantime, if you want tutoring on our boards, you'll need to take a picture of the complete exercise and attach it to your post. (See the FAQ for instructions.)

Thank you.
