Answer:

x = 0 , x = 3

Explanation:

y = - 2x(x - 3)²

to find the x- intercepts, where the graph crosses the x- axis, let y = 0

- 2x(x - 3)² = 0 ← product of factors on left

equate each factor to zero and solve for x

- 2x = 0 ⇒ x = 0

(x - 3)² = 0

x - 3 = 0

x = 3 with multiplicity 2

the x- intercepts are x = 0 and x = 3
