Answer:
If a quadratic function is not discriminating at 0, it does not have any real roots and it does not intersect the x-axis in the parabola it serves.
Step-by-step explanation:
The equation has no true solution if the discriminant is less than 0.
total is 240 then the bigger areas are 60* so S is 40*
i think it A
(5 square root 2-4 square root 3) (5 square root 2-4 square root 3)
= 98 - 40
i) (5 - 4) × (5√2 - 4√3)
=(5 × 5) - (5 × 4) - (4 × 5) + (4 × 4)
= 50 - 20 - 20 + 48
