Answer:
(- 3, 0 ) and (1, 0 )
Step-by-step explanation:
Given
y =2x² + 4x - 6
To find the x- intercepts let y = 0, that is
2x² + 4x - 6 = 0 ← divide all terms by 2
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 ) and (1, 0 )
