The discriminante :
b^2-4ac
1^2 - 4 * -2 * -28 = 1 - 224 = -223
When the discriminant (b^2-4ac) is less than 0, the equation had no real solutions.
-223<0, so, 2x^2+x-28 = 0 has no real solutions.
Hope that helps :)
The solution is x=1 and y=-2
Further explanation:
Given equations are:

Multiplying equation no. 1 with 2 will give us:
Eqn 3
From equation no 2:

Putting the value of y in eqn 3

The solution is x=1 and y=-2
