Question

find the roots of quadratic equation 2x2+x+4.​

Answer 1

Answer:

Its not a quadratic equation .

since the form of quadratic equation is ax^2+bx+c=0

but the question here is given that 'x+8'

Answer 2

Answer:

$a = 2 \: \: \: b = 1 \: \: \: \: c = 4 \\ {b}^{2} - 4ac = {1}^{2} - 4 \times 2 \times 4 \\ 1 - 32 = - 31$

$x = \frac{ - b± \sqrt{ {b}^{2} - 4ac } }{2a} = \frac{ - 1± \sqrt{ - 31} }{2 \times 2}$

Since there is negative sign in the root .

There are no roots for this equation.
