Question

X patrat-x+1=0 rezolvat in delta si a=?b=?c=?

Answer 1

x²-x+1=0
a=1;b=-1;c=1
Δ=b²-4ac=1-4=-3<0
S=∅

Answer 2

$\text{x}^2-\text{x}+1 = 0 \\ \\ \Delta = b^2-4ac = (-1)^2-4\cdot 1\cdot 1 = 1-4 = -3\ \textless \ 0 \Rightarrow \text{x}\notin \mathbb_{R} \\ \\ \\ a = 1;\quad b=-1;\quad c=1.$
