<h3>Given information-</h3>The given polynomial equation in the problem is,
Polynomial equation is a equation which is formed with coefficients variables and exponents with basic mathematics operation and equality sign.
In the above polynomial equation the variable are<em> x </em>and the highest power of the variable <em>x</em> is four.
Arrange the given polynomial equation in the power of the variable <em>x. </em>Thus,
Make the group of the same power of the variable <em>x. </em>Therefore,
From the given option the option C correctly combines the like terms and puts the given polynomial in standard form which is,
Hence the option C is the correct option.

Answer:
Step-by-step explanation:
When solving for x, we want to get x all by itself on one side of the equals side. It doesn't matter which side.
In this case, we have <em>x</em><em> </em><em>+</em><em> </em><em>h</em><em>.</em><em> </em>Since we want x alone we have to get rid of the h. We can do this by subtracting h from both sides (whatever you do to one side, you have to do to the other side).
Therefore, x = r - h.
