Question 172998: Write each polynomial in standard form. Then classify it by degree and by number of terms.
1. –x2 + 2x + x2
2. 7x2 + 10 + 4x3
3. 3x(4x) + x2(2x2)
Answer by midwood_trail(310)   (Show Source):
You can put this solution on YOUR website! 1. –x^2 + 2x + x^2
-x^2 + x^2 = 0
We are left with 2x
====================
2. 7x^2 + 10 + 4x^3
Put it in exponent descending order.
4x^3 + 7x^2 + 10
===================================
3. 3x(4x) + x^2(2x^2)
Use the distributive law to remove the parentheses.
12x^2 + 2x^4 becomes 2x^4 + 12x^2
Is this what you are searching for?
===================================
I don't know what you meant by "umm."
I answered your questions based on the information YOU provided.
For question (1), the polynomial is a first degree polynomial.
The highest exponent determines the degree of the polynomials.
For question (2), it is a third degree polynomial.
For question (3), it is a fourth degree polynomial.
Does this make sense to you?
