Answer:
(- 3, 0 ), (1, 0 )
Step-by-step explanation:
To find the x- intercepts, let y = 0, that is
3x² + 6x - 9 = 0 ( divide through by 3 )
x² + 2x - 3 = 0 ← in standard form
(x + 3)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 1 = 0 ⇒ x = 1
The x- intercepts are (- 3, 0 ), (1, 0 )
