Question 138045: How do you factor these equations:
x(squared) + 3x -4 =
y(squared) + 13y - 48=
And how would you solve these equations:
(x-3) (x-7)= 0
b(squared) + 3b - 4= 0
n(squared) + n - 12= 0
5x (squared) + 18x = 8
3a (squared) + 4a = 2a(squared) - 2a - 9

Question 143384: The problem is x(x+1)squared(x+2)=0; 0, -1, 2.
Sorry I dont know how to make an exponent on the computer. I am supposed to use the 0, -1, and 2. to determine by substitution which of the given numbers, if any satisfy the equation. So far I have getting that -1 and 0 work! I have a question about my work though. Am I supposed to distribute the x first or foil first? Thanks so much for your time! Tarah

Question 147759: (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!
