I really need help with this equation as soon as possible :D

viktelen [127]

The subtraction sign in front of the second set of parenthesis changes the signs on the terms inside those parenthesis. So this could be rewritten as $x-3x^4+2x^2+x^3-4x^6$ . None of the exponents on the x are the same, so we will just express it in terms of descending powers of x. $-4x^6-3x^4+x^3+2x^2+x$ . This is also the same as $4x^6+3x^4-x^3-2x^2-x$ if you don't like to start with a negative. Either one is correct.

If you were to randomly survey 1,000 people at a local grocery store about their use of corrective lenses, would this be a valid

gayaneshka [121]

You would probably need a little larger sample of people because not all people wear corrective lenses. In almost any other survey, this would be a scientist’s dream, but in this one, you’d need it to be a little bigger.

Why is the polynomial, 4x^2y + 5xy classified as a 3rd degree binomial?

Ronch [10]

The polynomial has two terms. The exponent of the first term is two. The exponent of the second term would be 1 because 5xy^1 is equal to 5xy.
