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.
Thanks.
...which will become: πx^3 - πx - 2x + 40
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?
No it does not, it is the combination of different shapes from a problem the finding the perimeter and areas of the shapes. The rest you know.
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.
