Removing factor of 1: 4z-2y/6-z explain how to solve this pleaseeeee

To simplify the expression 4z - 2y / 6 - z, you need to remove the factor of 1 from the denominator.

To do this, you can multiply both the numerator and the denominator by the conjugate of the denominator. The conjugate of 6 - z is 6 + z.

So, the expression becomes: (4z - 2y) * (6 + z) / (6 - z) * (6 + z)

Now you can simplify the expression further by multiplying the factors in the numerator and the denominator:

Numerator: (4z - 2y) * (6 + z) = 24z + 4z^2 - 12y - 2yz

Denominator: (6 - z) * (6 + z) = 36 - z^2

Therefore, the simplified expression is: (24z + 4z^2 - 12y - 2yz) / (36 - z^2)
