Question

sa se rezolve ecuatia bipatrata

x patrat - 6x + 25 = 0

Answer 1

[tex]x^2-6x+25=0\\ \triangle=(-6)^2-4\cdot 1\cdot25=36-100<0[/tex]=>ecuatia nu are solutii reale.

Answer 2

$x^{2} -6x+25=0\\Delta=36-4*25=-64\\ x_{1} = \frac{6-i \sqrt{64} }{2} = \frac{6-8i}{2} =3-4i\\ x_{2} = \frac{6+ i\sqrt{64} }{2} = \frac{6+8i}{2} =3+4i$
