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.
The question is very long, I don't think I would be able to type it here. But I am given the perimeter of a shape and I am supposed to find the area in terms of x, then find the value of x using calculus. You get the idea. I have used the given perimeter value to exclude the y value (by writing it in terms of x). Now I have the area in terms of x which I have differentiated to to give the result above.
Do you think it would be okay to use trail and improvement?
Yes the problem was the cubic expression, but I have solved that now and managed to complete the rest of the question.
Thanks for the help.
