Question

F(x)=4x 2 +2x+6 What is the value of the discriminant of f

Answer 1

Answer: -92

Explanation:

discriminant formula:
`b^2-4ac`

`f(x) = 4x^2+2x+6`

a = 4

b = 2

c = 6

`b^2-4ac\\2^2-(4(4)(6))\\4-(96)\\4-96\\-92`

Since the discriminant equals -92, and -92 is less than 0, we know the equation will not have real solutions
