find the x-intercepts for the parabola defined by the equation below.

y = 2x2 + 2x - 4

a.

(-4, 0) and (2, 0)

b.

(-2, 0) and (1, 0)

c.

(0, -2) and (0, 1)

d.

(0, -4) and (0, 2)

B. (-2, 0) and (1, 0)

Step-by-step explanation:

The equation can be factored as ...

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

The x-intercepts are the values of x where y=0, so will be the values of x that make one or the other of the binomial factors zero:

x = -2

x = 1

Then the intercept points are (-2, 0) and (1, 0). . . . . . . . . matches choice B
