A quadratic equation has a discriminant of 12. Which could be the equation?
1.) 0 = –x2 + 8x + 2

2.) 0 = 2x2 + 6x + 3

3.) 0 = –x2 + 4x + 1

4.) 0 = 4x2 + 2x + 1

Answered by maham237 @



Ax^2 + bx + c = 0, the discriminant

is b^2 - 4ac when I try to solve with option 2
6^2 - 4(2)(3) = 12
So the answer is 2
