Question

Illustrate the terms variables constant coefficient exponent degree of the polynomial for this expression by labelling the parts of the algebraic expressions: 1.25x² +6 5x³-20x² + x - 4

Answer 1

Welcome to Question Cove @hanjina. So what do we do first?

Answer 2

Yes I can so what is the first thing we have to do in the polynomial expression?

Answer 3

I believe you are right! So, you might wanna use pemdas to make this easier. (Parentheses, Exponents, Multiply, Divide, Add, Subtract!)

Answer 4

ok, so you don't have any parentheses, but you do have exponents, so take care of all the exponents first

Answer 5

I'm assuming this:6 5x³| is a 6.5x^3 ?

Answer 6

Anyway, you should have gotten:
1.25^2 = 1.5625x
6.5^3= 274.62500x
20^2=400x

Answer 7

So now instead of 1.25x² +6 5x³-20x² + x - 4, you have:
1.6x+274.625x-400x+x-4

If you deal with the x's first, your equation should turn into -122.77500-4

4 doesn't have an x, so you can't do anything with the two remaining numbers.

If this is wrong I am so sorry. I literally just did this question in class yesterday, and the teacher said I got it right, but hey everyone makes mistakes. Good luck!
