Question

Choose the polynomial that is written in standard form.
1.) −3x5y2 + 4x3y + 10x2
2.) −8xy2 + 4x4y2 + 3x3
3.) x4y2 + 4x3y5 + 10x4
4.) x6y2 + 4x3y8 + 10x7

Answer 1

Look at the exponents for the different terms. It should start with the heighest exponent and get lower. For example,
x^2 + 3x + 5 is in order
x^4 + x^5 -x+7 is not.
