## Sample Problems For Quadratic Formula

### Complexity=1, Mode=easy

Solve using the quadratic formula, separating answers with commas. Sample answers: "4,3/2", "4 + sqrt(4),4 - sqrt(3)", "(1+2sqrt(3))/2,(1-2sqrt(3))/2". If there is no solution, write "no solution".
 1.   -x 2 + 3x + 10 = 0 x = 2.   x 2 - 4 = 0 x =

### Complexity=1, Mode=normal

Solve using the quadratic formula, separating answers with commas. Sample answers: "4,3/2", "4 + sqrt(4),4 - sqrt(3)", "(1+2sqrt(3))/2,(1-2sqrt(3))/2". If there is no solution, write "no solution".
 1.   - 2x 2 + 6x + 8 = 0 x = 2.   -x 2 - 11x + 8 = 0 x =

### Complexity=1, Mode=easy

Solve using the quadratic formula, separating answers with commas. Sample answers: "4,3/2", "4 + sqrt(4),4 - sqrt(3)", "(1+2sqrt(3))/2,(1-2sqrt(3))/2". If there is no solution, write "no solution".
1-x 2 + 3x + 10 = 0
x =
Solution
Based on ax2 + bx + c, we have:
a = -1, b = 3, c = 10

Simplifying...

- 2, 5

2x 2 - 4 = 0
x =
Solution
Based on ax2 + bx + c, we have:
a = 1, b = 0, c = -4

Simplifying...

2, - 2

### Complexity=1, Mode=normal

Solve using the quadratic formula, separating answers with commas. Sample answers: "4,3/2", "4 + sqrt(4),4 - sqrt(3)", "(1+2sqrt(3))/2,(1-2sqrt(3))/2". If there is no solution, write "no solution".
1- 2x 2 + 6x + 8 = 0
x =
Solution
Based on ax2 + bx + c, we have:
a = -2, b = 6, c = 8

Simplifying...

- 1, 4

2-x 2 - 11x + 8 = 0
x =
Solution
Based on ax2 + bx + c, we have:
a = -1, b = -11, c = 8
