(x+2y+z) (x-2y-z)
= x^2 - 2xy - xz + 2xy - 4y^2 - 2yz + xz - 2yz - z^2 = x^2 - 4y^2 - 4yz -z^2

Say you have 7 divided by 3.5
7/3.5 If you set up like this 3.5 into 7, you move the decimal over once in 3.5
So you now have 35 into 7. Next you have to move the decimal on the seven however many times you moved the first decimal. So 7 is now 70
Next you just do simple division 35 into 70 =2
5x + 4y = -4
-5x -5x
4y= -5x - 4

4 4
y=-5/4x - 1
