B

Explanation:

I really think its b

Answer 2

We can use quadratic formula to determine the roots of the given quadratic equation.

The quadratic formula is:


`x= \frac{-b+- \sqrt{ b^(2) -4ac} }{2a}`

b = coefficient of x term = 4
a = coefficient of squared term = 1
c = constant term = 7

Using the values, we get:


`x= (-4+- √(16-4(1)(7)) )/(2(1)) \\ \\ x= (-4+- √(-12) )/(2) \\ \\ x= (-4+-2 √(-3) )/(2) \\ \\ x= -2+- √(-3)`

So, the correct answer to this question is option A
