I have a very long question but I am stuck on factorizing the value of the differentiation I have found to find the x value.
Here is the differentiation: 2πx^3 - 2πx - 4x +80.
Do you think it would be a good idea to multiply the π with 2 to remove it. The result will be a decimal value but that will be had to work with as well. This will affect the x values right.
