4. Simplify: (-z-2w2)(z-2)-1

-z⁻⁵w²

Step-by-step explanation:

(-z⁻²w²){(z⁻²)⁻¹}

simplify each first

{(z⁻²)⁻¹}  = z⁻²⁻¹ =  z⁻³

(-z⁻²w²) z⁻³

-z⁻² z⁻³ w²)

-z⁻²⁺⁽⁻³⁾w²

-z⁻²⁻³w²

-z⁻⁵w²

b

step-by-step explanation:

if a was wrong then it has to be b it cant be c either because not all the y intercepts are the same!
