Question

Find the x-intercepts for the parabola defined

by this equation:
y=-2x^2- 4x + 6
Write your answer as two ordered pairs:

Answer 1

(-3,0) ; (1,0)

Explanation:

We have to solve the associated equation:

-2x^2 -4x + 6 = 0

-x^2 - 2x + 3 = 0

x^2 + 2x -3 = 0

Δ/4 = 1 + 3 = 4

x1 = -1 + 2 = 1

x2 = -1 -2 = -3
