Question

Which of the following shows 8x³y + x² - 14z - 2 + 5y2x written in standard form?

-14z + 8x³y + 5y²x - 2 + x²
8x³y + 5y²x + x² - 14z - 2
8x³y + x² + 5y²x - 14z - 2
x²-2-14z + 5y²x + 8x²y

Answer 1

The correct answer is 8x³y + 5y²x + x² - 14z - 2.

Explanation:

This is in standard form because it is a polynomial with the terms arranged in descending order of their exponents, with the coefficient of each term being positive.

The exponent of x is 3, the exponent of y is 2, the exponent of z is 1, and the constant is -2.
