Question

factorise of 4x2-x+2​

Answer 1

Answer:

It doesn't have real roots but can be factorised in complex

Step-by-step explanation:

$= 4 {x}^{2} - x + 2$

Find its roots by Quadratic Formula

They are

$x = \frac{ - 1 + i \sqrt{31} }{8} \: \: or \: \: \frac{ - 1 - i \sqrt{31} }{8}$

Now, if a Quadratic equation is in the form

(x-a)(x-b)=0

Then a, b are roots, using the same concept

$= (x - \frac{( - 1 - i \sqrt{31} )}{8} )(x - \frac{( - 1 - i \sqrt{31} )}{8} )$
