Question

Choose the polynomial written in standard form.

x2y2 + xy − 1

10x3 + 14x2 − 4x4 + x

x2 + x2y + 3

5x + x3 − 3

Answer 1

I think this information will be our guide for this problem.

Answer 2

@Solmyr What do you think?

Answer 3

well from a couple of previous equations like this, i thought the exponents went from smallest to largest.

Answer 4

Of the options, I do not see one that behaves in the manner you described.

Answer 5

Yet, what is written in your study materials as "standard form of a polynomial" is what you should use.

Answer 6

well at first i was thinking C, x^2 + x^2y + 3

Answer 7

ok

Answer 8

x^2 + x^2y + 3 = x^2 + y*x^2 + 3 --I don't see that as an option but you could try it. Do you know how your resource materials define standard form of a polynomial.

Answer 9

This one appeals to me: x^2*y^2 + x*y − 1

The two variables are of equal power in the first term, second, and third term.
The third term could be thought of as --> -1* x^0 * y^0.

Answer 10

ok srry had to do something

Answer 11

No worries. I wrote above the option that appeals to me.

Answer 12

ok

Answer 13

so my answer will be A?

Answer 14

I cannot say for sure because you mentioned that your books or whatever showed standard form with increasing powers of the variable. However, I don't see any of the options that fit that. So, you might say I went with option A by default. None of the others seemed correct.

Answer 15

oh

Answer 16

i just went back to the lesson study and your right it is A

Answer 17

Glad that you checked the reference materials.
