What do "zeros" represent?

• something a polynomial can not be.

• the place that the polynomial crosses the x axis/ the x value that makes the whole equation equal to zero

• the place that the polynomial crosses the y axis/ the y value where x=0

• the number zero

For $\left(x+5\right)\left(x-1\right)=0$  , what is x equal to? (You can only select 1 answer!!!) 

• x=-5

• x=-4 x=1

• x=1

• x=1 and x=-5

• x=-1 and x=5

Which does not describe the zeros of a polynomial?

• Where a graph crosses the x-axis

• Also known as the roots

• Where x=0

• The solution when a factor is set equal to zero

There is always a zero on a polynomial if...

• Points to the left and right are both positive

• Points to the left and right are both negative

• One point either to the left or right is zero

• The x-value is zero

• Points to the left and right have opposite signs
