Subtract the polynomials: (6x3 - 4x + 2) - (2x3 - 1). Enter your answer as a polynomial in descending order below, and use the caret (^) for exponents. For example, you would write as 4x^2.

can someone plz help

OpenStudy (bahrom7893):

4x^3 - 4x +1

OpenStudy (anonymous):

you can only subtract like terms, "like" terms being the ones that are raised to the same power, i.e in the example above, 6x^3 and 2x^3. so we get: 4x^3 - 4x + 1

Which polynomial does this sum of tiles represent? A. 5x2 + 3x + 1 B. 2x2 + 5x + 1 C. 3x2 + 4 D. 2x2 + 3x + 1

OpenStudy (bahrom7893):

I don't get the question

OpenStudy (anonymous):

sorry hold on forgot to square

OpenStudy (anonymous):

Which polynomial does this sum of tiles represent? A. 5x2 + 3^x + 1 B. 2x^2 + 5x + 1 C. 3x^2 + 4 D. 2x^2 + 3^x + 1

OpenStudy (anonymous):

the 2 in question A is squared

OpenStudy (bahrom7893):

what do you mean which polynomial though? THey are all polynomials

OpenStudy (anonymous):

x^ x^ xxx 1

OpenStudy (bahrom7893):

I still don't get it sorry. What do you want me to do with those polynomials?

Find the sum of the polynomials below: (5x^5 + 2^x - 1) + (6x^5 + x + 8) A. 25x^25 + 3x^2 + 7 B. 11x^5 + 3x + 7 C. 25x^5 + 3x + 7 D. 11x^9 - 5x + 1

OpenStudy (anonymous):

does this one make sense

OpenStudy (bahrom7893):

yeah

OpenStudy (anonymous):

yay :)

OpenStudy (bahrom7893):

B

OpenStudy (anonymous):

thank you very much :)

Find the sum of (2x^2 + x + 1) and (2x^2 + 3x + 2). Enter your answer as a polynomial in descending order below, and use the caret (^) for exponents. For example, you would write as 4x^2.

OpenStudy (anonymous):

i hope this one does to

OpenStudy (bahrom7893):

4x^2 + 4x + 3

OpenStudy (anonymous):

ind the sum of the polynomials below: (4x^7 + 5x^5 + 1x + 6) + (10x^7 + 6x^5 - 4x + 4) A. 40x^7 + 30x^5 - 3x + 10 B. 40x^7 + 11x^5 - 3x + 10 C. 14x^7 + 11x^5 - 3x + 10 D. 14x^7 + 11x^5 + 3x + 10

OpenStudy (bahrom7893):

C

OpenStudy (anonymous):

wow your quick

OpenStudy (bahrom7893):

sorry was away, can u do ur own hw? LOL

OpenStudy (anonymous):

ok sure sorry i botherd u

OpenStudy (bahrom7893):

5x^2 +3x +4

OpenStudy (anonymous):

ok ill not bother you anymore thank you for all your help

OpenStudy (bahrom7893):

np
