Question

Solve.(z-2)(z-1)=0(If there is more than one solution, separate them with commas.)= 0Z=80,0,...Ś

Answer 1

We have the equation:

$(z-2)(z-1)=0$

There are a total of two options that complies the equation, as it is a product.

If the first term is 0, the equation is right.

But if the second term is 0, the equation is right too.

Then both are solutions.

So we have:

$z-2=0$$z=2$

And,

$z-1=0$$z=1$

Then we can conclude:

The two correct answers are z=2 and z=1

z=1,2 in the format asked.
