Answer: Find the discriminant
Check explanation
Step-by-step explanation:
b^2-4ac
if it is equal to 0 there is no solution
Greater then 0 there is 2 real solution
Less then 0 there is 1 real
3^2-4(2*-1)
9-4(-2)
9(8)
72 there is at least one real solution
Answer:
√306
Step-by-step explanation:

14 - 5 = 9
→ Use Pythagoras theorem
√15² + 9²
→ Simplify
√306
D and F and C are all equal D.360 F. 10yards = 360inches C. 30 feet = 350inches.
The a value affects the graph by vertically stretching or compressing the graph.
The r and s values affect the zeros, or x intercepts of the parabola, and therefore the vertex.
