Question :-Factorise x² - x + 4 = 0​

Answer 1

Step-by-step explanation:

we will use quadratic formula to find solution-

$\frac{ - b + \sqrt{b - 4(ac)} }{2a}$

$\frac{1 + \sqrt{( - 1) ^{2} - 4 \times (1 \times - 4)} }{2}$

substitute the values a=1 ,b=-1 and c=4

$\frac{x = 1 + \sqrt{17} }{2}$

$\frac{x = 1 + 17}{2} \: \: \: \frac{1 - \sqrt{17} }{2}$
