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)
