Answer:
D. 2x^2+ 6x +4= 0
Explanation:
The quadratic equation 2x²+6x+4 = 0 solutions will have opposite integers as shown.
On factorising:
2x²+6x+4 = 0
(2x²+2x)+(4x+4) = 0
Bringing out the common factor
2x(x+1)+4(x+1) = 0
(2x+4)+(x+1) = 0
2x+4 = 0 and x+1 = 0
2x = -4 and x = -1
x = -1/2 and -1
As we can see, the solution to the quadratic equation gave us two different integers. Note that the remaining functions will give the same values as the solutions.
