Answer:

If Δ = 3, then 4 x Δ = 12

If Δ = 6, then 4 x Δ = 24

If Δ = 5, then Δ - 5 = 0

If Δ = 5, then 14 + Δ = 19

If Δ = 8, then 6 + Δ - 4 = 10

If Δ = 0, then 54 x Δ = 0

If Δ = 7, then 7 x Δ = 49

If Δ = 89, then 1 x Δ = 89

Answer:

(0,0) and (-530,0)

Step-by-step explanation:

If you have to use the quadratic formula, you need to know your A, B, and C values. Your A value is 4, your B is 2120, and your C value, or constant, appears to be zero. Then you need to plug these values into the quadratic formula to get 0 and -530. This would make your roots to be at points (0,0) and (-530,0).
