Answer:

(-3,0) (1,0)

Step-by-step explanation:

y=2x^2+ 4x - 6

Factor out the greatest common factor

y = 2( x^2 +2x -3)

Factor inside the parentheses

y = 2( x+3)(x-1)

Setting the equation equal to zero to find the x intercepts

0 =  2( x+3)(x-1)

Using the zero product property

x+3 = 0  x-1 =0

x = -3  x = 1

The x intercepts are

(-3,0) (1,0)
