-23
Step-by-step explanation:
x2−x+6=0
Step 1: Find discriminant with a=1, b=-1, c=6.
b2−4ac
=(−1)2−4(1)(6)
=−23
Answer:
−23
Answer:
no solution
Step-by-step explanation
[tex]x^{2}-x+6=(x^{2}-2.\frac{1}{2}x+\frac{1}{4})+6-\frac{1}{4}=(x-\frac{1}{2})^{2}+\frac{23}{4}[/tex]
see : [tex](x-\frac{1}{2})^{2}\geq 0 => (x-\frac{1}{2})^{2}+\frac{23}{4}\geq 0+\frac{23}{4}>0[/tex]
but x² - x + 6 =0
=> it is unreasonable
