Question

Answer 1

`a, = x(x-y) - 8(x-y)`

`= (x-8)(x-y)`

`b, = x(y-z) + (y-z)`

`=(x+1)(y-z)`

Answer 2

`a, = x(x-y) - 8(x-y)` `= (x-8)(x-y)`

`b, = x(y-z) + (y-z) =(x+1)(y-z)`

Answer 3

\(b,=x\left(x-y\right)-8\left(x-y\right)\\ =\left(x-8\right)\left(x-y\right)\\ d,x\left(y-z\right)+\left(y-z\right)=\left(x+1\right)\left(y-z\right)\\ f,=2a\left(a-b\right)+a-b\\ =\left(2a+1\right)\left(a-b\right)\\ h,=a\left(b^2+2\right)-3\left(b^2+2\right)\\ =\left(a-3\right)\left(b^2+2\right)\)
