Question

Am nevoie de un raspuns la x² -3x + 2 = 0 repede va rog

Answer 1

x² -3x + 2 = 0
delta=($-3^{2}$-4*1*2=9-8=1
$x_{1}$=$\frac{-(-3)-\sqrt{1}}{2*1} = \frac{3-1}{2} = \frac{2}{2}=1$
$x_{2}= \frac{-(-3)+ \sqrt{1}}{2*1} = \frac{3+1}{2}= \frac{4}{2} =2$
Raspuns x1=1
                 x2=2

Answer 2

 x² -3x + 2 = 0 delta=1
x1=1
x2=2
