Dividing Polynomials with Long Division

How are you feeling?

5 - Positive, Well

3 - Neutral, I'm here

1 - Negative, Unwell

Dividing polynomials requires that your dividend be written both in standard form and such that no variable is missing between the largest and smallest exponent (in descending order). You must insert placeholders (zeroes) if a term(s) is missing in your dividend. Does the polynomial $$4x^2+23x-16$$  require any placeholders?

What step should you take to begin this problem.

After dividing $$4x^2$$  by x and writing 4x above 23x, what is the next step that you should take in solving this problem?

The next step you should take is to "subtract." What difference will you find?

Which selection is the final answer?

Consider the given polynomial $$x^2+3$$  . Does the polynomial require placeholders before long division can be performed? If yes, pick the correct placeholder.

Perform the given division problem. What is your final answer? Take your time, and show your work. This will be graded.
