Put the quadratic y = 3x2 + 5x + 1
into the quadratic formula: x = -b+Vb2-4ac
Enter the number that belongs in the green box
- [?]+v[ 12-40)
20
2a
X=

y = 3x² + 5x + 1

x = -b±√b²-4ac/2a

a = 3, b = 5 c = 1

x = -5±√5²-4(3)(1)/2(3)

x = -5±√25-12/6

x = -5±√13/6

i will take them

step-by-step explanation:

1

x = 1

step-by-step explanation:

0 ÷ x = 0
