Question

z^3-4z=0

Answer 1

We can factor a 'z' out of this since both terms have at least 1 'z'

\[\large z(z^2 - 4) = 0\]

Now we can see there are 3 different solutions to this equation

Answer 2

ok

Answer 3

Since we have 'z' being multiplied to whatever is in those parenthesis, we know that 'z' = 0 is actually a solution to this...since 0 times anything = 0

Now we just focus on the parenthesis

\[\large z^2 - 4 = 0\]

What 2 values of 'z' make this equation = 0?

Answer 4

ok
