Step-by-step explanation:

ax2 + bx + c = 0

x12 = (-b ± √D) / 2a , D = b2 - 4ac .

5x2 + 7x + 3 = 0

a = 5 , b = 7 , c = 3

D = 49 - 60 = - 11 , x1 = (-7 - i √11) / 10

x2 = (-7 + i √11) / 10

An ice cream shoppe charges $1.19 for a scoop of ice cream and $0.49 for each topping. Jeb paid $4.55 for a three scoop sundae.
AysviL [449]
He bought 3 scoops, each costing $1.19
The cost of the three scoops= 3*1.19= $3.57

Total cost of scoops and toppings is $4.55
Cost of toppings only= 4.55-3.57= $0.98
Each topping costs $0.49

Therefore number of toppings bought= 0.98/0.49= 2

Answer: 2 toppings
