Question 147759This question is from textbook
: (2z+5)(4z-10z+25)
The 4z is supposed to be squared but I can't figure out how to type that on here.
The portion of the chapter where this problem is found is called Creating the Sum and Difference of Cubes. It gives you a short cut for finding the solution, but does not give any detail to help me figure out how they reached the answer. I can not except the solution they want me to give without knowing what is done to reach that answer. They give the solution in the end of the chapter and I understand why the first and last terms are what they are, but can not figure out why the middle term disappears. Please help!
