Heyy can you please help me posted picture of question
vichka [17]
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= \frac{-4+- \sqrt{16-4(1)(7)} }{2(1)} \\  \\ 
x=  \frac{-4+- \sqrt{-12} }{2}   \\  \\ 
x= \frac{-4+-2 \sqrt{-3} }{2} \\  \\ 
x= -2+- \sqrt{-3}

So, the correct answer to this question is option A
