Question

What are the zeros of the function f(x) = x2 + 8x + 4, expressed in simplest radical form?

Answer 1

x = –4 ± 2
`√(3)`

Explanation:

Answer 2

Explanation:

assuming it is
`x^(2) +8x+4`

Using Quadratic formular -

a - 1

b - 8

c - 4

`x= ( -8 -,+ √((8^2) - 4 (1)(4)))/(2(1)) \\\\`

`x = (-8 +,- √(48) )/(2)\\\\`

`x = (-8+,- 4√(3) )/(2)`

`x = {-4+,- 2√(3) }`
