i've been trying to work through my math assignment and i'm stuck on certain questions. How would you do these??(If i put ^ before an # its an exponent)
1. b^2  b  63
2. 3x(y  z) 2(y  z)
3. (y^2  y) (xy  x)
If you could help...it'd be appriciated

1. b^2  b  63 doesn't factor in rational numbers.
2. 3x(y  z) 2(y  z)
Factor out the common factor (or use the distributive property, depending on how you look at it):
(y  z) (3x  2)
3. (y^2  y) (xy  x)
Factor out the common factors:
y (y  1) (x) (y + 1)
I don't understand the additional question.
